Poly[tetrabutylammonium [chloridohexamethyl-μ3-sulfato-distannate(IV)]]

Abstract

In the structure of the title coordination polymer, {(C16H36N)[Sn2(CH3)6Cl(SO4)]}n, the two independent SnIV atoms are coordinated in a trigonal–bipyramidal manner by three methyl groups in the equatorial plane and in the axial positions by either two O atoms of bridging SO42− anions or by a Cl atom and one O atom of a bridging SO42− anion, respectively. The [Sn2(CH3)6Cl(SO4)]− anion forms an infinite zigzag chain parallel to the c axis. The cations are situated between these chains. Two of the four butyl groups of the cation are partially disordered over two sets of sites with site occupancies of 0.79 (2):0.21 (2) and 0.75 (2):0.25 (2), respectively. Weak C—H...O hydrogen-bonding interactions help to consolidate the crystal packing.
