Two novel trimethylsulfonium salts with polymeric {[SbCl4]−}nor {[CdCl3]−}nanions

Abstract

The title organic–inorganic hybrid salts poly[trimethylsulfonium [[dichloridoantimony(III)]-di-μ-chlorido]], {(C3H9S)[SbCl4]}n, (I), andcatena-poly[trimethylsulfonium [cadmium(II)-tri-μ-chlorido]], {(C3H9S)[CdCl3]}n, (II), consist of trimethylsulfonium cations and polymeric {[SbCl4]−}nor {[CdCl3]−}nanions. The central metal atoms are coordinated by six Cl atoms, forming an anionic {[SbCl4]−}nthree-dimensional framework (two of the four bridging chloride anions are located on two different centres of inversion) or anionic {[CdCl3]−}none-dimensional chains. The trimethylsulfonium cation of (II) is disordered over two sets of sites in a 0.791 (4):0.209 (4) ratio. All the anions are linked by trimethylsulfonium cations through weak C—H...Cl hydrogen bonds to form three-dimensional structures.
