摘要:
The title compound, [Zn(C14H8O6S)(H2O)(2)](n), is the first reported metal complex of the 4,4'-sulfonyldibenzoate anion. The structure comprises zigzag chains of alternating [Zn(H2O)(2)]](2+) and sulfonyldibenzoate units, the central Zn and S atoms of which lie on crystallographic twofold axes. The Zn-II centre occupies a strongly distorted tetrahedral environment [O-Zn-O = 83.30 (7)-136.19 (8)degrees], coordinated by the two water O atoms [Zn-O = 1.986 (2) angstrom] and one O atom from each of two carboxylate groups [Zn-O = 1.9942 (19) angstrom], with much longer contacts to the other O atoms of these carboxylates [Zn-O = 2.528 (2) angstrom]. Hydrogen bonds between carboxylate O atoms and coordinated water molecules in adjacent chains lead to the formation of a three-dimensional network structure.
