Abstract: The title compound, [Co(C₇H₄NO₄)₂(H₂O)₄], consists of one cobalt cation, two 4-hydroxypyridine-2,6-dicarboxylate ligands, and four coordinated water molecules. The geometry around the cobalt(II) cation, which is located on a centre of inversion, is distorted octahedral. The four coordinated water molecules and the hydroxyl atoms from the ligand form intermolecular hydrogen bonds, resulting in a three-dimensional supramolecular network.
