Structural studies on indium and tin thiobenzoates

Article abstract of DOI:10.1002/cber.19961290918

Indium(III) and tin(IV) thiocarboxylates were prepared and characterized on the basis of their IR, ¹³C- and ¹⁹Sn-NMR data. Indium tris(thiobenzoate) (1) decomposes into a sulfido complex In(S)(S(O)CPh] (2a). The corresponding tris(thioacetate) In[S(O)CMe]₃ is thermally too unstable to be isolated. The anionic tetrakis complex [Et₃NH]iIn[S(O)CPh]₄) (3) was characterized by X-ray crystallography which revealed a distorted tetrahedral coordination at the In atom. X-ray diffraction analysis of the complexes BuSn[S(O)CPh]₃ (4) and Cl₂Sn[S(O)CPh]₂ (7) showed distorted tetrahedral and tis-octahedral structures, respectively. VCH Veriagsgesellschaft mbH, 1996.
