【Abstract】 Abstract In this paper, a new compound [Co(en)3]2· 2H3O· [As8V14O42(HPO4 )]. 2H2O was obtainedby hydrothermal method at 140℃ for 5d, which was characterized by IR, ICP and single crystal X-raydiffractinn. The titled compound is crystaIlized 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, D.=2. 289 Mg/m3, M,=2 586. 19, μ= 5. 703 mm-1, F(000) = 9 788, R=0. 088 9, wR=0. 248 2. The tetrahedron PO4 is in-cluded in an anion cage which is formed via condensed vanadium oxygen square pyramids(VO,) and octa-hedral(VO6) connected by As2O5 units through sharing oxygen atoms. The two Co cation is coordinatedby three en respectively, in which the six N atoms of the three en form an octahedron with Co atom as thecentre.
