The compound crystallizes in the monoclinic, space group C2/c, a=1.7633(2)nm, b=1.00122(11) nm, c=1.37624(13)nm, β=96.974(5)°, V=2.4117(5)nm3, Z=4, Dc=2.853g·cm-3, μ(MoKα)=2.766mm-1, F(000)=1992. The structure contains the isolated polyanions of [Mo5O15(HPO4)2]4- units around which the portonated ethylenediamine ions are pos itioned. By hydrogen bond interactions the polyanions are interconnected to form a three dimensional network. Other characterizations by powder XRD, IR and thermal analysis are also described.
