Abstract

Reaction of triphenyltin(IV) chloride with monothiobenzoic acid results in the formation of triphenyl (monothiobenzoato) tin (IV), C25H20OSSn, which crystallizes in the orthorhombic system, space group P212121 (No. 19), with a = 8.2959(8), b = 16.900(4), c = 31.453(2) Å, V = 4410(1) Å3, Dc = 1.468g cm−3, F(000) = 1952, μ = 12.64 cm−1 for Z = 8. Refinement converged to R = 0.037 and Rw = 0.041 (w = [σ2(F) + (0.02F)2 + 1]−1) based on 3282 unique reflections and 2191 observed reflections such that l > 3σ(l). The ligand functions as a monodentate anion coordinating to the tin atom through its sulphur atom and conferring a tetrahedral geometry about the tin atom. The average bond length between tin and sulphur is 2.430(5)Å.
