X-ray single crystal analysis reveals FJ-10 belongs to a triclinic crystal system, space group P-1, a=1.038 18(6) nm, b= 1.230 41(7) nm, c=1.234 81(7) nm, α=97.207 0(10)°, β=109.411 0(10)°, γ=113.081 0(10)°, V=1.307 79(13) nm 3, R 1=0.039 9, wR 2=0.101 3. The topology structure of FJ-10′s framework is characterized by PO 3(OH) bridged 4-rings. FJ-10 exemplifies firstly the π-π stacking of hybrid chains whose structure-building units are involved in ZnO 3N 2. FJ-10 predicts the novel hybrid transition phosphates.展开更多

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.
