摘要
控制不同反应条件，川芎嗪与ＰｄＣｌ２可以反应得到不同颜色的晶体，经过Ｘ－射线结构分析，证实了它们为不同的反应产物：ＰｄＬ２Ｃｌ２（Ⅰ）和（ＬＨ２）ＰｄＣＩ４·４Ｈ２Ｏ（Ⅱ）［Ｌ＝Ｔｃｔｒａｍｃｔｈｙｌｐｙｒａｚｉｎｅ：Ｃ８Ｈ（１２）Ｎ２］．
nder the different reaction conditions, the different colour crystals have been obtained by the reactions between tetramethylpyratine and PdCl2. It was determined that two crystals really belong to different crystals by X-ray diffraction method. PdL2Cl2(L=Tetramethylpyrazine)belongs to monoclinic with space group Cc and cell parameters: a = 13.536(4)A, b = 15.372(5)A, c= 9.425(3)A, p= 105.79(2) o,V= 1887.4(10)A3, Z=4. (LH2)PdCl4·4H2O belongs to monoclinic with space group C2 and cell parameters: a=8.715(3)A, b= 17.392(4)A,c= 6.713(2)A, β= 112.03(2)°,V= 943.2(4)A3, Z=2
