Catena-Poly[[di-n-butyltin(IV)]-μ-trifluoromethanesulfonato-[[di-n-butyl(trifluoromethanesulfonato)tin(IV)]-di-μ-hydroxo

Abstract

The solid-state structure of the title compound, [Sn2(CF3O3S)2(C4H9)4(OH)2]n, consists of an infinite chain of dimeric hydroxo di-n-butyl­tin(IV) complexes bridged by trifluoro­methane­sulfonate ligands. The X-ray crystallographic analysis reveals the presence of seven- and six-coordinate tin(IV) units. The structure contains two types of trifluoro­methane­sulfonate ligands, viz. bridging and terminal. The uncoordinated O atoms of terminal O3SCF3 are involved in both intra- and inter­molecular hydrogen bonding with the bridging hydroxo ligands. The resulting two-dimensional network can be seen as a superimposed three-layer structure along the a axis.
