A CuII coordination polymer, catena-poly[[[aquacopper(II)]-bis(μ-4-aminobenzoato)-K2N:O;K2O:N] monohydrate], {[Cu(pABA)2(H2O)]·H2O}n (pABA = p-aminobenzoate, C7H4NO2- ), was synthesized and characterized. It exhibits a one-dimensional chain structure extended into a three-dimensional supramolecular assembly through hydrogen bonds and π–π interactions. While the twinned crystal shows a metrically orthorhombic lattice and an apparent space group Pbcm, the true symmetry is monoclinic (space group P2/c), with disordered Cu atoms and mixed roles of water molecules (aqua ligand/crystallization water). The luminescence spectrum of the complex shows an emission at 345 nm, cf. 349 nm for pABAH. |
