摘要 由二甲胺与H6P2W18O62·nH2O合成了电荷转移化合物α H6P2W18O62·3(CH3)2NH·H2O.单晶结构解析结果表明晶体属单斜晶系,空间群为P21／c,晶胞参数:a=1.2964(3)nm,b=1.3621(3)nm,c=4.1559(8)nm,β=90.02(3)°,V=7.338(3)nm3,Z=4.标题化合物具有可逆光色性.热分析表明,化合物阴离子在430.5℃左右分解. A charge-transfer complex, α-H_6P_2W_(18)O_(62)·3(CH_3)_2NH·H_2O, has been synthesized and characterized. The single crystal X-ray structure analysis of the title compound reveals that it belongs to monoclinic system, space group P2_1/c with a=1.296 4(3) nm, b=1.362 1(3) nm, c=4.155 9(8) nm, β=(90.02)(3)(°), V=7.338 (3) nm^3, and Z=4. The compound is strongly photosensitive under irradiation of sunlight. TG/DTA analysis reveals that the compound decomposes at 430.5 ℃.
