Abstract

The title compound [(H3NCH2CH2NH3)][(VO) 3(H2O)2(PO4)2(HPO 4)] was synthesized from the hydrothermal reaction of V2O5:V:H3PO4:H2NCH 2CH2NH2:H2O in the mole ratio of 1:1:10:5:740. The compound crystallizes in the triclinic space group P1̄ with unit cell parameters a=10.187(1),b=10.241(1),c=8.2137(7) Å,α=90.398(8),β=95.930(9) and γ=117.325(7)°°,V=755.7(1) Å3,Z=2, Dcalc=2.570 g cm-3, R=0.032, Rw=0.035. The data were collected by using ω-2θ scan technique and the structure was solved by direct method. The structure consists of binuclear units of corner-sharing [VO6] octahedra and square-pyramidal [VO5] units linked by phosphate tetrahedra, forming double extended polyhedral slabs in the (101) plane with these slabs connected by corner-sharing [HPO4] tetrahedra to form a corner-sharing three-dimensional cage structure about the diammonium cations.
