Three new diorganotin(IV) selenites, [BuSn(OSeCHOMe)] ( 1), [MeSn(OSeCHCHMe)] ( 2), [MeSn(OSeCHEt)] ( 3) have been synthesized and structurally characterized by elemental analysis, FT-IR, NMR (H, C and Sn) spectra, TGA, and X-ray crystallography. The X-ray reveals that complexes 1-3 are 1D infinite double-chain polymers. The molecular of complex 1 is further linked by intermolecular C-H···O interactions to form a 2D network polymer. Complex 3 is linked by C-H···O interactions to form a 3D organotin framework. [ABSTRACT FROM AUTHOR]

The synthesis and structural characterization of four novel triorganotin(IV) complexes, {(RSn)[CHS(COO)]} (R = Me: 1), {(RSn)[CHS(COO)]} (R = nBu: 2), {(RSn)[CHS(COO)]} (R = Me: 3; nBu: 4) were obtained by the reaction of 2,2′-thiodiglycolic acid, 3,3′-thiodipropionic acid and the corresponding RSnCl (R = Me, nBu) with potassium hydroxide in methanol. All the complexes were characterized by elemental analysis, Fourier transform infrared and nuclear magnetic resonance (H, C, Sn) spectroscopies, X-ray crystallography and thermogravimetric analyses. The crystal structures show that 1 has 2D network structure in which 2,2′-thiodiglycolic acid acts as a tetradentate ligand coordinating to the trimethyltin(IV) ions. Complexes 2, 3, and 4 are 3D metal-organic framework structures in which the deprotoned acids act as a tetradentate ligand afforded by four oxygen atoms. [ABSTRACT FROM AUTHOR]

novel sulphate of organotin was synthesized by the reaction of triphenyltin chloride with silver sulphate. The structure of {[(PhSn)SO] · HO)} · 2EtOH has been determined by X-ray crystallography. The crystal data parameters are as follows: monoclinic, space group Cc, a = 14.146(6), b = 23.844(11), c = 23.777(11) Å, Z = 4. The title compound displays a dimeric tetra-tin nuclear structure. The geometry about tin is trigonal bipyramidal with a trans-OSnC stereochemistry about the metal. Hydrogen bonding between the oxygen atoms of the anion and the solvate water produces a graphite-like 3D network lattice. [ABSTRACT FROM AUTHOR]

new organotin(IV) Schiff base complex 4 containing a novel SnO hydrolysis ladder and a disulfide group has been synthesized through a self-assembly reaction. The complex 4 has been characterized by elemental analysis, IR, H-, C-, and Sn-NMR spectra and X-ray crystallography diffraction analyses. The study of the supramolecular structure of complex 4 found that there exist two kinds of C-H···S and C-H···O intermolecular hydrogen bonds. The two kinds of intermolecular hydrogen bonds force the complex 4 into a 2-dimensional 'wave' network. The geometry about each tin atom involved is distorted trigonal bipyramid.
