B-frame-supported bimetallics. Isoelectronic arachno-structured [(PMe2Ph)4Pd2B8H10] and closo-structured [(PMe3)4(CO)2Ir2B8H8]

Abstract Reaction of [IrCl(CO)(PMe 3 ) 2 ] with [NEt 4 ][ nido -B 9 H 12 ] gives the ten-vertex eight-boron cluster species [(PMe 3 ) 4 (CO) 2 Ir 2 B 8 H 8 ]. This formally has a closo cluster electron count compatible with its closo structure. By contrast, ten-vertex eight-boron [(PMe 2 Ph) 4 Pd 2 B 8 H 10 ], isolated from [4-(NH 2 Ph)- arachno -B 9 H 13 ] and [PdCl 2 (PMe 2 Ph) 2 ], has a closo electron count but an arachno structure. The origins of this apparent anomaly are briefly addressed and enunciated.

Polyhedral oxaplatinaborane chemistry: characterisation of [9,9-(PMe2Ph)2-arachno-9,6-PtOB8H10] and its metallaborane non-oxa cognate [6,6-(PMe2Ph)2-arachno-6-PtB9H11-9-(PMe2Ph)]

Abstract Reaction of [(PMe2Ph)2PtB8H12] with KH and [{(η5-C5Me5)RhCl2}2] followed by chromatographic separation in air unexpectedly gave the ten-vertex oxametallaborane [9,9-(PMe2Ph)2-arachno-9,6-PtOB8H10] (1, 11%), which has a classical arachno ten-vertex geometry with the {O} and{Pt(PMe2Ph)2} vertices in the prow (6)- and (9)-positions; the oxygen atom is therefore bound contiguously to boron atoms only. Reaction of [PtMe2(PMe2Ph)2] with [6,9-(PMe2Ph)2B10H12] generates its ten-vertex metallaborane cognate [6,6-(PMe2Ph)2-arachno-6-PtB9H11-9-(PMe2Ph)] (3, 10%), and completes a coherent B→C→N→O cluster constituent sequence. Compounds 1 and 3 are characterised by single-crystal X-ray diffraction analysis and NMR spectroscopy.

Macropolyhedral boron-containing cluster chemistry. [PtMe2(PMe2Ph)2] as a cluster metallating agent. Isolation and characterisation of nineteen-vertex [(PMe2Ph)HPt-η4-syn-B18H19(PMe2Ph)] and eighteen-vertex [(PMe2Ph)2PtS2B15H14(NHCOMe]

Abstract [PtMe 2 (PMe 2 Ph) 2 ] reacts quantitatively with [ nido -B 10 H 14 ], [ arachno -4-SB 8 H 12 ] and [ nido -7-SB 10 H 12 ] to give [(PMe 2 Ph) 2 PtB 10 H 12 ], [(PMe 2 Ph) 2 PtSB 8 H 10 ] and [(PMe 2 Ph) 2 PtSB 10 H 10 ]. With [ syn- B 18 H 22 ] it gives nineteen-vertex [(PMe 2 Ph)HPt- η 4 - syn -B 18 H 19 (PMe 2 Ph)] 1 and only smaller amounts of [(PMe 2 Ph) 2 Pt- η 4 - syn -B 18 H 20 ], whereas with [( anti )-9,9′-S 2 B 16 H 16 ] a complex product mixture is generated from which eighteen-vertex [(PMe 2 Ph) 2 PtS 2 B 15 H 14 (NHCOMe)] 1 is isolatable after treatment with MeCN in air.

Performing ‘Ostalgie’: Leander Haussmann's Sonnenallee

The following article examines Leander Hausmanns hit youth comedy Sonnenallee (1999). In particular it attempts to challenge many reviewers who saw the film as nothing more than a self-indulgent piece of ‘Ostalgie’ which trivialises the oppressive reality of life in the GDR. Instead, it argues that the film deliberately highlights the competing tensions at work within contemporary nostalgia for the East German state. On the one hand, Sonnenallee constructs ‘Ostalgie’ as a response to fears among many East Germans that the true nature of their everyday experience is being elided from the historical record. Through the use of an intricate network of Eastern and Western cultural references, the film attempts to counter this impulse by highlighting the importance of both these cultural traditions to youth in the GDR. In so doing the film translates the experience of East Germans into a cultural language that West Germans will understand, thereby ‘normalising’ this experience. On the other hand, and seeming to contradict this project, the film also challenges simplistically rose-tinted views of the East. Consequently, the film forces the East German spectator to reflect upon, and ultimately reject, any manifestations of Ostalgie which would ostensibly call for a return to the GDR.

Polyhedral ruthenaborane chemistry. The ten-vertex isocloso cluster geometries of [(pcym)RuB9H9] and [(pcym)2Ru2B8H8]

Abstract [1-(pcym)-isocloso-1-RnB9H9] and [1,5-(pcym)2-isocloso-1,5-Ru2B8H8] constitute the first structurally characterised ‘clean’ monometalla and bimetalla examples of the parent ten-vertex isocloso metallaborane structural type.

B-frame supported bimetallics. ‘Composite cluster’ compounds and the structures of [2,7-(η5-C5Me5)2-nido-2,7,8,6-Ir2CSB6H8] and its 9-chloro derivative. Synchrotron and conventional X-ray studies

Abstract Reaction of [IrCl 2 (η 5 -C 5 Me 5 )] 2 with the [ hypho -CSB 6 H 11 ] − anion gives [2,7-(η 5 -C 5 Me 5 ) 2 - nido- 2,7,8,6-Ir 2 CSB 6 H 8 ] and [2,7-(η 5 -C 5 Me 5 ) 2 - nido- 2,7,8,6-Ir 2 CSB 6 H 7 -9-Cl] which exhibit composite cluster features in which the {IrSIrC} string and the {B 6 } unit occupy separate domains within the overall contiguous nido -type ten-vertex {Ir 2 SCB 6 } cluster unit.

B-frame supported bimetallics. [(PMe2ph)2PtB9H11Ru(η6-isoPrC6H4Me)] and [(PMe2ph)2PtB9H9Ru(η6-isoPrC6H4Me)]; an interesting pair of electron-deficient nido and closo geometries

Abstract [7,7-(PMe 2 Ph) 2 -9-( η 6 - iso PrC 6 H 4 Me)-7,9-PtRuB 9 H 11 ] has a formal closo Wadian cluster-electron count, but a nido geometry, whereas [1-( η 6 - iso PrC 6 H 4 Me)-4,4-(PMe 2 Ph) 2 -1-4-RuPtB 9 H 9 ], which does have a closo geometry, has a formal sub- closo cluster electron count; both compounds are formed in the reaction between [6-( η 6 - iso PrC 6 H 4 Me)- nido -6 RuB 9 H 13 ], KH and [PtCl 2 (PMe 2 Ph) 2 ].

Experiencing the Digital World: The Cultural Value of Digital Engagement with Heritage

Since the late 1990s the potential of the digital world for generating new ways of engaging with heritage, broadly defined, has been a key focus of academic work and cultural practice. At times, the emphasis has been on how the internet can provide a “shop window” for the sector, and how this might be translated into physical visits to sites. Elsewhere, scholars have argued that the digital sphere can provide a dynamic space for two-way engagement with heritage culture, aimed at providing a complementary experience to physical visits through a range of phenomena (e.g. user-generated content, online communities, crowdsourcing projects). Questions have also been raised about how to measure the value of this activity and what we mean by value in this context. We bring together literature on digital engagement, interactivity and participation within heritage, case studies of current practice, and a survey of heritage professionals to focus on six key areas: 1. Financial resources2. Relative value of the digital experience3. The location of culture value4. Cultural value and time5. Enhanced value through participation6. Cultural value, space, and placeWe present strategies that heritage organizations of different scales might consider incorporating into new digital resources, while also suggesting further areas for research. Primarily, we suggest that there is substantial untapped potential to better understand the experience of end users by harnessing the vast amount of data that is available within heritage institutions, but which organizations frequently do not have the resources to exploit.

Supporting Contemporary German Film: How Triumphant is the Free Market?

This article examines the way the film industry is supported in Germany, looking at the complex array of public funding available, the types of films this support tends to produce and what the future might hold for film-makers. I question the claim that the industry has moved from a subsidy-based model, which promoted avant-garde Autorenkino, to a market-driven model that is more in line with Hollywood, with an emphasis on mainstream mass entertainment. Instead, I argue that the industry is more reliant than ever on the public subsidy system, even as this system ostensibly looks to promote a market-oriented approach to film-making.

Complexes of gold, silver and copper withZ,Z-PPh2CH2CButN–NC(But)CH2PPh2 containinga nine-membered chelate ring: crystal structure of[AuCl{Z,Z-PPh2CH2CButN–NC(But)CH2PPh2}]

Complexes of gold, silver and copper with the azine diphosphine Z,Z-PPh 2 CH 2 CBu t N–NC(Bu t )CH 2 PPh 2 have been prepared and shown to contain the diphosphine in an unusual nine-membered chelate ring; the crystal structure of the chlorogold derivative [AuCl{Z,Z-PPh 2 CH 2 CBu t N–NC(Bu t )CH 2 PPh 2 }] was determined.
