Catena-Poly[[aqua-trimethyl-tin(IV)]-{[trimethyl-tin(IV)]-?(3)-thio-phene-2,5-dicarboxyl-ato}].

ABSTRACT: In the title compound, [Sn(2)(CH(3))(6)(C(6)H(2)O(4)S)(H(2)O)](n), each of the two crystallographically independent Sn atoms exhibits a distorted trigonal-bipyramidal coordination geometry formed by two O and three C atoms. The coordinated water mol-ecule plays an important role in crystal packing consolidation via O-H?O hydrogen bonding.

Both Fe(II) atoms lie on crystallographic centers of symmetry. The complex possesses an infinite chain structure running along the [101] direction. These chains are inter-connected by the uncoordinated water mol-ecules through O-H⋯O hydrogen bonds.
