Abstract: A novel 3D diorganotin framework, {[(nBu2Sn)2(dmsa)]2 ·MeOH} n (1), has been solvothermally synthesized and structurally characterized by elemental analysis, FT-IR, NMR (1H, 13C, 119Sn) spectra, TGA and X-ray crystallography. The structure analysis of complex 1 reveals that guest methanol molecules are established in the hydrophobic “pseudo-channels” of this framework. [Copyright &y& Elsevier]

Abstract: A series of new triorganotin(IV) complexes with 4-hydroxy-2-mercapto-6-methylpyrimidine (L1H2), 4-hydroxy-2-mercapto-pyrimidine (L2H2), 2,4(1H,3H)-pyrimidinedithione (L3H2) () of the type R3SnLSnR3 (R=Me 1, 4, 7; R=Ph 2, 5, 8; R=PhCH2 3, 6, 9) have been synthesized by reactions of triorganotin(IV) chloride and corresponding ligands. All complexes are characterized by elemental analyses, IR spectra and NMR spectra analyses. Among them, complexes 2, 5 and 8 are also characterized by X-ray crystallography diffraction analyses. Significant π⋯π stacking, C–H⋯π interactions and intramolecular hydrogen bonds stabilize these structures. [Copyright &y& Elsevier]

Abstract: A series of diorganotin (IV) complexes of the types of R2SnCl(SSCC3H3N2) (R=CH3 1, n Bu 2, C6H5 3 and C6H5CH2 4), R2Sn(SSCC3H3N2)2 (R=CH3 5, n Bu 6, C6H5 7 and C6H5CH2 8) and R2Sn(SSCC3H2N2) (R=CH3 9, n Bu 10, C6H5 11 and C6H5CH2 12) have been obtained by reactions of 4(5)-imidazoledithiocarboxylic acid with diorganotin (IV) dichlorides in the presence of sodium ethoxide. All complexes are characterized by elemental, IR, 1H, 13C and 119Sn NMR spectra analyses. Also, the complexes 1, 7 and 9 are characterized by X-ray crystallography diffraction analyses, which reveal that the complex 1 is monomeric structure with five-coordinate tin (IV) atom, the complex 7 is monomeric structure with six-coordinate tin (IV) atom and the complex 9 is one-dimensional chain with five-coordinate tin (IV) atom.
