Investigation on steric effect in the coordination of S, N and O donor heterocycle to organotin(IV): Syntheses and crystal structures of triorganotin(IV) derivatives with 5-phenyl-1,3,4-oxadiazole-2-thiol
摘要:
A series of organotin(IV) complexes with 5-phenyl-1,3,4-oxadiazole-2-thioI of the type R3Sn[S(C8H5N2O)] (R = Me 1, n-Bu 2, PhCH2 3, Cy 4, Ph 5) have been synthesized. All the complexes 1-5 have been characterized by elemental, IR, H-1 NMR, C-13 NMR analyses and X-ray crystallography. Among them, the central tin atoms of complexes 1-5 are all five-coordinated with distorted trigonal bipyramidal geometry. Interestingly, complexes 1-4 exhibit 1D polymeric chains through Sn and N intermolecular interactions. (c) 2005 Elsevier Ltd. All rights reserved.
