Abstract
The new compound, (H3O)2[Cu3Cl3(H2O)3(NCgH12.5O6)2] 1, has been synthesized by the hydrothermal reaction and its structure was determined by single-crystal X-ray diffraction.The crystal is of hexagonal, space group P63/m with a = 10.6975(13), c = 14.881 (3)A, V = 1474.8(4)866, R = 0.0517 and wR = 0.0900 for 537 observed reflections (I ＞ 2σ(Ⅰ)). This compound contains two oxonium ions and one [Cu3C13(H2O)3(H0.5ntp)2]2- anion (ntp = nitrilotripropanoato), in which two tridentate ntp ligands connected by three copper(Ⅱ) ions enclose a cage-like unit. Each copper(Ⅱ) ion is coordinated by one water molecule, one chloride ligand and two carboxylate oxygen atoms from two ntp ligands assume a slightly distorted square-planar geometry. There are atoms of the units resulting in two-dimensional sheets and wheel-like three-dimensional interpenetrating frameworks.
