摘　　要：在水溶液中合成了一个B型Anderson结构CrMo杂多阴离子的二甲亚砜溶剂化合物,其分子式为:(NH4)3H3(CrMo6O24H6)2(C2H6SO)6.X射线单晶分析表明,该化合物属三斜晶系,P1空间群,主要晶胞参数为:a=1.4289(3)nm,b=1.4295(3)nm,c=1.6263(3)nm,α=63.93(3)°,β=90.00(3)°,γ=60.05(3)°,R=0.0398.TG曲线表明,化合物失重分三步进行,化合物最后分解温度在494.41℃.Cr-Mo miscellaneous polyanion and dimethyl sulfoxide solvent compound with B type Anderson structure were synthesized in aqueous solution.The molecular expression is (NH_4)_3H_3(CrMo_6O_ 24H_6)_2(C_2H_6SO)_6. The single crystal was analyzed by X-ray and the results of experiment show that the compound is a triclinic crystal system with P1 space group. The chief crystal cell parameters tested by TG means are a= 1.428 9(3) nm, b= 1.429 5(3) nm, c= 1.626 3(3) nm, α= 63.93(3)°, β= 90.00(3)°, γ= 60.05(3)°, R= 0.039 8. The curves show that the compound weight lost underwent three procedures. At last the compound was decomposed at 494.41 ℃.
