摘　　要：以磷钼酸和N,N-二甲基苯胺为原料合成了一种有机-无机电荷转移盐[C6H5(CH3)2NH]3·[PMo12O40]·1.5H2O.用IR、UV、X射线单晶衍射技术对其进行了表征.标题化合物的晶体结构属于单斜晶系,空间群P2(1)/n,晶胞参数为a=1.18078(3)nm,b=2.55985(8)nm,c=1.79515(6)nm,α=90.00(°),β=94.97(6)(°),γ=90.00(°),V=5.4055(3)nm3,Z=4,Dc=2.723mg.m-3,F(000)=4220,μ(MoKα)=2.821mm-1,R1=0.0528,wR2=0.1459.An charge-transfer salt _3··1.5H_2O has been synthesized and characterized by IR, UV and X-ray crystallography. The crystal belongs to monoclinic, space group P2(1)/n, a=1.18078(3) nm, b=2.55985(8) nm, c=1.79515(6) nm, α=90.00 (°),β=94.97(6) (°), γ=90.00 (°), V=5.4055(3) nm^3, Z=4, Dc=2.719 mg·m^(-3), F(000)=4208, μ(MoKα)=2.821 mm^(-1). The structure has been refined to R_1=0.0528 and wR_2=0.1459 by full-matrix least-squares method. There are hydrogen bonds between bridge/terminal oxygen atoms and nitrogen atoms of N,N-bimethyl-aniline or oxygen atoms of water molecules.
