Poly[[aqua­[μ-1,4-bis­(3-pyridylmeth­yl)piperazine-κ2N:N′](μ-isophthalato-κ2O1:O3)copper(II)]

In the title compound, [Cu(C8H4O4)(C16H20N4)(H2O)]n, square-pyramidally coordinated CuII ions are linked into [Cu(H2O)(isophthalate)]n coordination polymer chains by isophthalate dianions. These chains are connected into undulating [Cu(H2O)(isophthalate)(3-bpmp)]n [3-bmp is bis(3-pyridylmethyl)piperazine] layers by 3-bpmp tethering ligands. The pseudo three-dimensional structure of the title compound is fostered by interlayer 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.
