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.
