metal-organic compounds
The 4,4′-bipyridine spacer in the crystal structure of the title compound, {[Cu(C10H8N2)2(H2O)]2(C8H4O4)·2H2O}n, links the water-coordinated CuI atoms into a linear chain in which the metal atom exists in a T-shaped environment [N—Cu—N = 156.6 (1)°]. Interacting through the coordinated water molecules, the chains connect with the centrosymmetric terephthalate dianions and uncoordinated water molecules to form a three-dimensional network structure.
metal-organic compounds
The Zn atom in the title compound, [Zn(H2O)6](C6H4NO3)2, lies on a special position of 2/m site symmetry in an octahedron made up of water molecules. The anion is disordered across a mirror plane. The cation interacts with the anion indirectly through hydrogen bonds to form a three-dimensional network.
