A novel ribbon-candy-like supramolecular architecture of cadmium(II)–terephthalate polymer with giant rhombic channels: twofold interpenetration of the 3D 8210-a net

The hydrothermal reaction of H2tp (tp = terephthalate), [Ph3PCH2Ph]Cl and water with Cd(O2CCH3)(2).2H2O gives rise to a novel ribbon-candy-like supramolecular architecture with twofold interpenetration of an unprecedented 3D 8(2)10-a net formed by polymer ([Ph3PCH2Ph][Cd(tp).Cl].2H2O]n containing giant rhombic channels, which displays strong fluorescent emission in the solid state.

Interpenetration in [Cd(isonicotinate)2(1,2-bis(4-pyridyl)ethane)0.5(H2O)]n, a novel octahedral polymer containing an unusual two-dimensional bilayer motif generated by self-assembly of rectangle building blocks

A hydrothermally synthesized mixed-ligand molecular solid composed of pillared bilayers has been formulated; it presents a new remarkable three-dimensional architecture sustained by the catenation of two-fold decked layers, and exhibits intense photoluminescence upon photoexcitation at 314 nm.

Synthesis, structure and fluorescence of a 3-D polymer {(Mo4O12)(4,4′-bipy)2}n

Abstract We report the synthesis, single-crystal X-ray structure, IR, TGA–DTA and fluorescence of a black MOF crystal {(Mo4O12)(4,4′-bipy)2}n, which has two channels. One channel along the [001] direction was formed by a metaloxygen octatomic ring and the another one along the [010] direction was shaped by 4′4-bipy.

Two new coordination host frameworks for the inclusion of 4-amino-benzophenone guest molecules

Abstract The synthesis and structural characterization of novel organometallic coordination polymers are reported. The reaction of Cd(NO3)2 and 4,4′-bipy in CH3OH/H2O gave a 2D coordination network formulated as {[Cd(4,4′-bpy)2·(H2O)2](NO3)2·4H2O}10, which was used to capture an organic guest species (4-amino-benezopheone, C13H11NO (3)) to obtain {[Cd(4,4′-bpy)2(NO3)(H2O)]·NO3·(C13H11NO)2} (1). Using L (L=4,4′-trimethylenedipyridine) instead of 4,4′-bipy, {[Cd(L)2(H2O)2]·2H2O·2NO3·C13H11NO} (2) was synthesized, which has an interesting configuration.

The first octanuclear tin(IV)-oxosulfide cluster

Abstract The first octanuclear tin(IV)–oxosulfide complex (NH 4 ) 2 (Et 4 N) 4 [Sn 8 S 12 O 4 (SPh) 6 ] has been synthesized by mixing stoichiometric amount of Sn(SPh) 4 and (NH 4 ) 2 WOS 3 and thiophenol in DMF. The compound was crystallized in orthorhombic space group Cmcm, Z=4, a=18.0463(4) A , b=15.7599(2) A , c=19.1914(5) A , a single crystal X-ray diffraction analysis revealed two coordinate modes of the tin atoms: five-coordinated distorted rectangular pyramid SnOS 4 and six-coordinated octahedron SnO 3 S 3 .

Synthesis and structures of two novel heterometallic polymers

Abstract The cyanide act as a bridging ligand between metal atoms and it usually gives to polymeric compound with 2D or 3D networks, two novel heterometallic polymers containing CN ligands {[Et4N]2[WS4Cu4(CN)2Br2]}n (1) and [ZnCu4(CN6(dmf)4]n (2) have been synthesized and characterized in this paper.

The syntheses and structures of two hexanuclear copper(II) complexes with amino acids

Hexanuclear copper(II) complexes with amino acids have been synthesized and the structures can be described as cages with pseudocubic Oh symmetry in which six copper ions are bound by eight tridentate amino acids with one Na+ in the center of the cage.

Novel hexamercaptotin: synthesis and characterization of [N(CH3)4]2Sn(SH)6 and [N(C2H5)4]2Sn(SH)6 complexes

Abstract Mercaptotin complexes are difficult to synthesize since they are usually transient intermediates. Here, we report the synthesis and crystal structure of two examples of stable hexamercaptotin complexes [N(CH 3 ) 4 ] 2 Sn(SH) 6 ( 1 ) and [N(C 2 H 5 ) 4 ] 2 Sn(SH) 6 ( 2 ), and discuss their stability by use of quantum chemistry method. Both the complexes 1 and 2 were obtained by hydrothermal synthesis and were crystallized in monoclinic space group, C2/m, Z =8, a =25.724(8), b =18.183(6), c =9.097(3) for 1 , and C2/c, Z =4, a =14.0733(14), b =14.4018(14), c =13.2538(13) for 2 . Single crystal X-ray diffraction analysis revealed that the Sn(IV) centers of 1 and 2 are octahedrally coordinated to six [SH] − ligands and all of the six hydrosulfuryl groups are located in terminal positions. The computational results of quantum chemistry method show that highly symmetric coordination of [SH] − ligands can be effective in stabilizing stannanethiols entities.
