The new compound, (H3O)2[Cu3Cl3(H2O)3(NC9H12.5O6)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) ?, V = 1474.8(4) ?3, C18H31Cl3Cu3N2O15?2(H3O), Mr = 850.47, Z = 2, Dx = 1.915 g/cm3, μ = 2.495 mm-1, F(000) = 866, R = 0.0517 and wR = 0.0900 for 537 observed reflections (I > 2σ(I)). This compound contains two oxonium ions and one [Cu3Cl3(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 O–H…Cl hydrogen bonding interactions between unligated oxonium ions and ligated chlorine atoms of the units resulting in two-dimensional sheets and wheel-like three-dimensional interpene- trating frameworks.
