In the title compound, [Cd2(C6H8O4)2(C16H20N4)(H2O)4]n, pentagonal-bipyramidally coordinated CdII ions are connected into {Cd2(2,2-dimethylsuccinate)2(H2O)4} centrosymmetric dimeric clusters. In turn, these clusters are linked by tethering 1,4-bis(3-pyridylmethyl)piperazine (3-bpmp) ligands into [Cd2(2,2-dimethylsuccinate)2(3-bpmp)(H2O)4]n coordination polymer chains. The chain motifs are oriented parallel to [10]. Individual chains are connected into supramolecular layers via O—HN and O—HO hydrogen-bonding mechanisms.

In the title compound, [Co(NCS)2(C16H16N4O2)]n, the octahedrally coordinated CoII ion lies on a crystallographic inversion center, with trans isothiocyanate ligands. Pyridyl N-donor atoms and formyl O-donor atoms from exotetradentate bis(4-pyridylcarbonyl)piperazine (4-bpfp) ligands link the Co(NCS)2 units into a [Co(NCS)2(4-bpfp)]n coordination polymer layer that is oriented parallel to (101). The layers stack along [010] to construct the pseudo-three-dimensional structure.
