Abstract
Three types of methyltin phosphonates, {[(CH 3) 3Sn] 4(O 3PPh) 2} n ( 1), {[(CH 3) 3Sn] 2(O 3PPh) · CH 3OH} n ( 2) and {[(CH 3) 2SnO 3PPh] 4} n ( 3) were synthesized by the reaction of phenylphonic acid with trimethyltin (IV) chloride and dimethyltin (IV) dichloride, respectively. Complexes 1, 2 and 3 were characterized by elemental analysis, IR, NMR ( 1H, 13C, 31P and 119Sn) spectroscopy, TGA and X-ray crystallography diffraction analysis. The X-ray analysis of complex 1 shows that the structure is a polymeric infinite 1D zigzag chain. In complex 2, the oxygen atom of methanol molecule is coordinated to the tin atoms, and a 2D network is generated via O–H⋯O hydrogen bonds. In complex 3, a novel 2D network containing 12-membered (Sn 3O 6P 3) rings is formed.
