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= 2.4825(9) nm, b=2.0994(8) nm, c=2.8866(9) nm, V=15.009(9) nm3, Z=8, Dc=2.289 Mg/m3, Mr=2586.19, μ= 5.703 mm-1, F(000) = 9788, R=0.0889, wR=0.2482.The tetrahedron PO4 is in-cluded in an anion cage which is formed via condensed vanadium oxygen square pyramids(VO5) 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 Natoms of the three en form an octahedron with Co atom as thecentre.
