Abstract: A new compound [H2en]2[H3O]6[Co（H2O）2（VO）8（OH）4（PO4）8] has been hydrothermally synthesized. Single crystal X-ray analysis indicates that this compound crystallizes in a monoclinic system, space group P21/n with a=1.438 5(3) nm, b=1.012 2(2) nm, c=1.832 5(4) nm, β=90.21°, V=2.668 2(9) nm3, Z=2, Dc=2.112 g/cm3, R=0.055, wR=0.149 7, S=1.037. The structure of [H2en]2[H3O]6[Co（H2O）2（VO）8（OH）4（PO4）8] is characterized by P-V-O layers constructed by [(VO)4(OH)2(PO4)4]6- non-symmetric units. The P-V-O layers are pillared by [Co(H2O)2]2+ group, resulting in the channels within which the protonated diaminoethane and H3O+ are located.

Key words: Hydrothermal synthesis, Layered compound, Crystal structure
