✦ Synopsis

In the crystal structure of the polymeric title compound, [Co(C~10~H~8~O~5~)(C~10~H~8~N~2~)(H~2~O)]~n~, the Co^II^ atom is O,O′-chelated by the aromatic carboxylate end of the 3-(4-carboxylatophenoxy)propionate dianion, and is covalently bonded (through one O atom) by the aliphatic carboxylate end of another dianion; it is also coordinated by a water molecule to give an octahedral coordination environment. The compound adopts a helical chain structure that propagates along the c axis of the orthorhombic unit cell. The coordinated water molecule engages in both intrachain and interchain hydrogen bonding; the interchain hydrogen bonds result in a honeycomb motif. The crystal structure is an inversion twin and the ratio of the two twin components refined to 0.47 (2):0.53 (2).
