N2 - A novel polyoxometalate [Co(C2N2H8) 3]4[MoV2MoVI 14VIV16O80(PO4) 2]·10H2O 1 has been hydrothermal synthersized from the rection mixture of V2O5, CoCl2· 2H2O, Na2MoO4·2H2O, ethylenediamine(en), H3PO3 and H2O in a reasonable yield(48%). The X-ray crystallography shows that 1 containing two types of typical heteropoly anions: tetra-capping Keggin anions and hexadecametal host shell anions. This is the first structurally characterized example of a heteropoly compound containing two types of anions. In compound 1, the Co2+ cations are coordinated by three ethylendiamine ligands, and [Co(en)3]2+ cations link the metal-oxygen cluster anions, to form a extensive three-dimensional supramolecular assembly through the hydrogen bonding. Compound 1 crystallallizes in the tetragonal with space group I4/mcm, a=b=19.6613(19), c=33.738(5) Å, V=13042(3) Å3.
