A zirconium arsenate compound with composition [Zr3(AsO4)4(H2O)2] H2O was synthesized by the reaction of zirconium tetrapropoxide and arsenic acid under mild hydrothermal conditions and its structure was solved from the X-ray powder diffraction data. The compound crystallizes in the triclinic space group P1 with a = 8.846(1), b = 9.393(1), c = 5.5352(7), = 92.504(2), = 91.353(3), = 108.267(2) and Z = 1. The structure consists of two octahedrally coordinated zirconium atoms, one of which is bound only by arsenate oxygens and the other by arsenate oxygens and water molecules. The bridging of zirconium atoms by arsenute oxygens creates a one-dimensional channel structure. The channels are filled with lattice water molecules that are hydrogen bonded to themselves as well as to the coordinated water molecule. 1998 Elsevier Science B.V.
