abstract

  • In this paper, a new compound [Co(en)3]2 • 2H3O • [As8V14O42(HPO4)] • 2H2O was obtained by hydrothermal method at 140°C for 5 d, which was characterized by IR, ICP and single crystal X-ray diffraction. The titled compound is crystallized in orthomgonal system, space group Pbca with a = 2. 482 5 (9) nm, b = 2. 099 4(8) nm, c = 2. 886 6(9) nm, V = 15. 009(9) nm3, Z = 8, Dc = 2. 289 Mg/m3, Mr = 2 586. 19, μ = 5. 703 mm-1, F(000) = 9 788, R = 0. 088 9, wR = 0. 248 2. The tetrahedron PO4 is included in an anion cage which is formed via condensed vanadium oxygen square pyramids (VO5) and octahedral(VO6) connected by As2O5 units through sharing oxygen atoms. The two Co cation is coordinated by three en respectively, in which the six N atoms of the three en form an octahedron with Co atom as the centre.
