(Received 23 April 2012; accepted 26 April 2012; online 2 May 2012)

The 1,10-phenanthroline-chelated Co^II 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.

Comment top

The title cobalt(II) compound (Scheme I, Fig. 1) is isostructural with the manganese(II) derivative, which we reported recently (Fang et al., 2011). The 1,10-phenanthroline chelated Co^II atom is connected to the sulfonate O atom of one (C₇H₄O₆S) dianion and to the carboxylate O atom of another dianion. It is also coordinated by two water molecules in an octahedral environment. The dianion links adjacent metal atoms into a chain along [1 1 0]. The chains are linked by O–H···O hydrogen bonds into a three-dimensional network (Table 1).

Experimental top

A methanol solution (5 ml) of 1,10-phenanthroline (1 mmol) was added to an aqueous solution (10 ml) of cobalt(II) dichloride (1 mmol), 2-hydroxy-5-carboxybenzenesulfonic acid (2 mmol) and lithium hydroxide (4 mmol). Pink crystals were isolated from the solution after several days.
