title: catena-Poly[[diaqua-cadmium(II)]bis-(μ-2,2-dimethyl-butane-dioato-κO,O':O'',O''')[diaqua-cadmium(II)]-μ-1,4-bis-(3-pyridylmeth-yl)piperazine-κN:N].
abstract: In the title compound, [Cd(2)(C(6)H(8)O(4))(2)(C(16)H(20)N(4))(H(2)O)(4)](n), penta-gonal-bipyramidally coordinated Cd(II) ions are connected into {Cd(2)(2,2-dimethyl-succinate)(2)(H(2)O)(4)} centrosymmetric dimeric clusters. In turn, these clusters are linked by tethering 1,4-bis-(3-pyridylmeth-yl)piperazine (3-bpmp) ligands into [Cd(2)(2,2-dimethyl-succinate)(2)(3-bpmp)(H(2)O)(4)](n) coordination polymer chains. The chain motifs are oriented parallel to [10]. Individual chains are connected into supra-molecular layers via O-H⋯N and O-H⋯O hydrogen-bonding mechanisms.
