The title cobalt(II) coordination polymer, poly[[diaquacobalt(II)]-mu(4)-3,3'-(p-phenylene)diacrylato], [Co(C12H8O4)-(H2O)(2)](n), was obtained by reaction of Co(NO3)(2)center dot 6H(2)O and 3,3'-(p-phenylene) diacrylic acid (H2L) under hydrothermal conditions. Each Co II cation sits on a centre of inversion and is hexacoordinated by six O-atom donors in an octahedral geometry. The Co II centres are connected by four centrosymmetric L2- anions, resulting in a three-dimensional framework structure. The coordinated water molecules and carboxylate O atoms form hydrogen-bond interactions, stabilizing the structure of the three-dimensional framework. Topologically, the framework represents a rare example of the three-dimensional 4-connected CdSO4 network type. The metal cations and the organic ligand both show in-plane coordination with respect to the extended structure.
