Synthesis and crystal structure [Cd(phen)_3]_2[PMo~VMo_(11)~VIO_(40)] and H_3O[Co(phen)_3]_2[PMo_2~VMo_(10)~VIO_(40)]

Two new unprecedented Keggin-type polyoxometalate [Cd(phen)_3]_2[PMo~ⅤMo_(11)~ⅥO_(40)] and H_3O[Co(phen)_3]_2[PMo_2~ⅤMo_(10)~ⅥO_(40)] were synthesized at mild hydrothermal condition,and the structure was characterized by elemental analysis,single crystal X-ray diffraction and IR.Compound(Ⅰ) crystallized in the monoclinic,space group P-1,a=1.200 5(2) nm,b=1.327 8(3) nm,c=1.356 7(3) nm,α=103.56(3)°,β=91.37(3)°,γ=97.72(3)°,V=2.079 8(7) nm3,Z=1,R1=0.044 2,wR2=0.140 3.Compound(Ⅱ) crystallized in the monoclinic,space group P-1,a=1.207 9(2)nm,b=1.380 4(3)nm,c=1.442 1(3)nm,α=104.81(3)°,β=109.63(3)°,γ=93.13(3)°,V=2.163 3(8)nm3,Z=1,R1=0.071 7,wR2=0.234 1.
