title: Poly[[aqua-[μ-1,4-bis-(3-pyridylmeth-yl)piperazine-κN:N'](μ-isophthalato-κO:O)copper(II)].
abstract: In the title compound, [Cu(C(8)H(4)O(4))(C(16)H(20)N(4))(H(2)O)](n), square-pyramidally coordinated Cu(II) ions are linked into [Cu(H(2)O)(isophthalate)](n) coordination polymer chains by isophthalate dianions. These chains are connected into undulating [Cu(H(2)O)(isophthalate)(3-bpmp)](n) [3-bmp is bis-(3-pyridylmeth-yl)piperazine] layers by 3-bpmp tethering ligands. The pseudo three-dimensional structure of the title compound is fostered by inter-layer O-H⋯O hydrogen bonding between the aqua ligands and unligated isophthalate O atoms. The selected crystal was non-merohedrally twinned. Only reflections from the major twin component were used in the solution and refinement.
