The Crystal and Molecular Structure of Dichlorobis(2-pyridinethiolato)tin(IV)

Abstract

Abstract The crystal and molecular structures of dichlorobis(2-pyridinethiolato)tin(IV) have been determined by X-ray analysis. The crystal belongs to the triclinic system: a=8.340(8), b=12.456(7), c=7.178(3) Å, α=86.46(4), β=111.06(5), γ=99.18(6)°, space group P\bar1 with Z=2. The structure was determined by the heavy atom method and refined by the block-diagonal least-squares method (R=0.058). The complex is a distorted octahedral complex in which 2-pyridinethiolato ligands act as bidentate ligands, two four-membered (Sn, S, C, and N) chelate rings being present. Two Sn–Cl bonds are cis, two Sn–N bonds are cis, and two Sn–S bonds are trans configuration.
