| Abstract: | A charge-transfer complex, α-H6P2W18O62·3(CH3)2NH · H2O, 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 P21/c with a =1.2964(3) nm, b =1.3621(3) mn, c =4. 1559(8) nm, β =90.02(3)(°), V =7.338 (3)nm3, and Z =4. The compound is strongly photosensitive under irradiation of sunlight. TG/DTA analysis reveals that the compound decomposes at 430.5 ℃. |
