Thermal expansion properties of three isostructural co-crystals composed of isosteric components: interplay between halogen and hydrogen bonds

Co-crystallization of a symmetrical azo bipyridine with isosteric resorcinols affords isostructural co-crystals that exhibit linear thermal expansion along each axis. The thermal expansions involve interplay between intra-layer halogen and hydrogen bonds.

Organosulfonates aid argentophilic forces in the crystal engineering of [2+2] photodimerisations: reactivity involving 3-pyridyl groups

Photoreactive Ag(I) organosulfonate complexes involving (E)-methyl-3-(pyridin-3-yl)prop-2-enoate (3-PAMe) are reported. Argentophilic interactions stack 3-PAMe to undergo a head-to-head intermolecular [2+2] photodimerisation to generate (rctt)-dimethyl-3,4-bis(pyridine-3-yl)cyclobutane-1,2-dicarboxylate (3,3′-MeBPCD) in the solid state regioselectively and in quantitative yield. The organosulfonate participates in C–H…O interactions with the coordinated 3-pyridyl groups to effectively aid in crystal engineering of the reactivity.

Hybrid Material Based on the Lindquist Polyoxometalate [W6O19]2− and the organosulfur donor o-Me2TTF: A Combined Structural and Spectroscopic Study

The synthesis, crystal structure and spectroscopic properties of the hybrid radical cation salt containing oxidized o-3,4-dimethyltetrathiafulvalene (o-Me2TTF) and the Lindquist polyoxometalate anion [W6O19]2− are reported. The title salt represents the first time a Lindquist polyoxometalate has been utilized as the counter anion with this unsymmetrical member of the TTF family of derivatives. The salt crystallizes in the triclinic space group

Utilizing Perylene in New Organic Donor–Acceptor Materials: Highlighting the Synthesis, Structure and Physical Properties of Perylene-pDNB and Perylene-TCNP

P1¯with axa0=xa07.6211(7)xa0Å, bxa0=xa09.5231(9)xa0Å, cxa0=xa012.2148(11)xa0Å, αxa0=xa0105.5870(10)°, βxa0=xa0106.8340(10)° and γxa0=xa095.6950(10)°. Resolution of the solid state structure revealed that the o-Me2TTF radical cations aggregate as isolated face-to-face dimers with intradimer interactions between neighboring sulfur atoms at distances <3.6xa0Å. Hydrogen bonding was also observed between hydrogen atoms bound to sp2-hybridized carbon atoms of o-Me2TTF and bridging oxygen atoms of [W6O19]2−. Single crystal IR and Raman spectra were also collected and provide further evidence that the o-Me2TTF donors have been oxidized to their corresponding radical cationic states.Graphical AbstractHerein we present the structure and single crystal spectroscopic properties of the hybrid salt (o-Me2TTF)2[W6O19], which combines the unsymmetrical TTF derivative o-Me2TTF with the closed shell Lindquist polyoxometalate [W6O19]2−.

Identification and Analysis of a New Organic Donor–Acceptor Material: Synthesis, Structure, Spectroscopy and Transport Properties of the 2:1 Complex o-Me2TTF–pDNB

With its close proximity of Hg(II) atoms, elevated electron-withdrawing properties and accessibility to electrophilic sites on its molecular surface, cyclic trimeric perfluoro-ortho-phenylenemercury (o-(C6F4Hg)3) has been identified as one of the simplest Lewis acids. Given the marrying of these effects within the molecule, it has consistently demonstrated facility in forming supramolecular complexes with both neutral and anionic substrates. In an effort to expand the library of neutral substrates complexed by (o-C6F4Hg)3, in this communication we highlight the structural and spectroscopic properties of the complex between (o-C6F4Hg)3 and the organic acceptor TCNB (TCNBxa0=xa01,2,4,5-tetracyanobenzene). The supramolecular complex crystallized in the centrosymmetric triclinic space group
