A new one-dimensional CuIIcomplex with a three-dimensional supramolecular architecture incorporating benzene-1,3-dicarboxylate and 1-[(1H-benzotriazol-1-yl)methyl]-1H-imidazole.
Subtle modifications of N-donor ligands can result in complexes with very different compositions and architectures. In the complex catena-poly[[bis{1-[(1H-benzotriazol-1-yl)methyl]-1H-imidazole-κN3}copper(II)]-μ-benzene-1,3-dicarboxylato-κ3O1,O1':O3], {[Cu(C8H4O4)(C10H9N5)2(H2O)]·2H2O}n, each CuIIion is six-coordinated by two N atoms from two crystallographically independent 1-[(1H-benzotriazol-1-yl)methyl]-1H-imidazole (bmi) ligands, by three O atoms from two symmetry-related benzene-1,3-dicarboxylate (bdic2-) ligands and by one water molecule, leading to a distorted CuN2O4octahedral coordination environment. The CuIIions are connected by bridging bdic2-anions to generate a one-dimensional chain. The bmi ligands coordinate to the CuIIions in monodentate modes and are pendant on opposite sides of the main chain. In the crystal, the chains are linked by O-H...O and O-H...N hydrogen bonds, as well as by π-π interactions, into a three-dimensional network. A thermogravimetric analysis was carried out and the fluorescence behaviour of the complex was also investigated.
