Abstract: | A novel layered supramolecular compound Ni(L)(TPHA)]·8H2O, containing two-dimensional (2D) water clusters and terephthalato-bridged ligand, where L = 1,3,6,9,11,14-hexaazatricyclo12.2.1.16,9] octadecane, TPHA = terephthalate dianion, has been synthesized and structurally characterized by spectroscopy and X-ray crystallography. The complex is neutral, in which the nickel(II) ions are bridged by the TPHA to form a one-dimensional (1D) infinite chain structure, and containing the eight-member water cluster. The presence of octameric water clusters have effectively increased the 1D coordination polymer to a three-dimensional layered structure. Every water cluster is connected strongly by a O–H···O hydrogen bond (range of the bonds between 2.724 and 3.056 Å). The complex crystallizes in monoclinic, space group P21/c with a = 9.788(3), b = 13.030(4), c = 11.646(4) Å, and β = 104.551(5)°. |
