The CoII cation in poly[[aqua(-benzene-1,2-dicarboxylato- 3O1,O2:O1)(-4,40-bipyridine-2N:N0)cobalt(II)] trihydrate], {[Co(C8H4O4)(C10H8N2)(H2O)]3H2O}n, is octahedrally coordinated by two N atoms of two 4,40-bipyridine ligands, three O atoms from phthalate anions and a fourth O atom from a coordinated water molecule. The packing consists of planes of coordination polymers linked by hydrogen bonds mediated by three solvent water molecules; the linkage is achieved by the water molecules forming intricate oligomeric clusters which also involve the O atoms of the phthalate ligands.
