Abstract

The 1,10-phenanthroline-chelated CoII atom in the polymeric title compound, {[Co(C7H4O6S)(C12H8N2)(H2O)2]·1.5H2O}n, is connected to the sulfonate O atom of one 4-hydroxy-3-sulfonatobenzoate dianion and to the carboxylate O atom of another dianion. It is also coordinated by two water molecules in a trans-CoN2O4 octahedral environment. The dianion links adjacent metal atoms into a chain running along [110]. The chains are linked by O—H⋯O hydrogen bonds into a three-dimensional network.
