【Abstract】 The novel polyoxometalate, 32[Mo8ⅣMo4ⅤV2ⅣO38(PO4)], was synthesized and characterized by elementary analysis, EPR, IR spectra and X ray diffraction. The compoundcrystallizes in triclinic system, space group with a= 1.41999(2)nm, b=1.43467(2)nm, c=1.694610(10)nm, α=95.7250(10)°, β=92.2110(10)°, γ=92.6060(10)°, V=3.42829(7)nm3, Z=2, Dc=2.388g·cm-3, Mr=2465.10g·mol-1, μ=2.489mm-1, F(000)=2388, R1=0.0584, wR2=0.1461, S=1.164. The heteropolyanion is a bi capped pseudo Keggin complex. CCDC: 186645.更多还原
