Poly[tetra­butyl­ammonium [chlorido­hexa­methyl-μ(3)-sulfato-distannate(IV)]]

In the structure of the title coordination polymer, {(C(16)H(36)N)[Sn(2)(CH(3))(6)Cl(SO(4))]}(n), the two independent Sn(IV) 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 SO(4) (2−) anions or by a Cl atom and one O atom of a bridging SO(4) (2−) anion, respectively. The [Sn(2)(CH(3))(6)Cl(SO(4))](−) 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.
