catena-Poly[[diaqua-copper(II)]-μ-hy-drox-ido-κO:O-μ-[4-(4H-1,2,4-triazol-4-yl)benzoato]-κN:N]
Abstract:
The title compound, [Cu(C(9)H(6)N(3)O(2))(OH)(H(2)O)(2)](n), adopts a chain motif along [010] in which the Cu(II) atoms are bridged by hy-droxy groups and 4-(1,2,4-triazol-4-yl)benzoate (tab) ligands. The Cu(II) atom lies on an inversion center and is six-coordinated by two N atoms from two tab ligands, two hy-droxy groups and two water mol-ecules, giving a distorted octa-hedral geometry. The hy-droxy group and the tab ligand are located on a mirror plane. One of the water H atoms is disordered over two positions with equal occupancy factors. Inter-molecular O-H⋯O hydrogen bonds extend the chains into a layer parallel to (100) and C-H⋯O hydrogen bonds connect the layers into a three-dimensional network.
