摘    要:用8-羟基喹啉、醋酸铜与硅酸钠分别在四氢呋喃和甲醇溶液中反应,生成了两种8-羟基喹啉合铜的配合物.溶剂为四氢呋喃时得到了含有两个配位水的蓝色的晶体Cu(C9H6NO)2·(2H2O)(Ⅰ);溶剂为甲醇时得到的却是不含水的双核的黑色晶体Cu2(C9H6NO)4(Ⅱ),两种晶体的晶胞参数不同.该文通过X射线单晶衍射分析了8-羟基喹啉合铜晶体结构,并用红外、热重、元素分析等方法进行了结构表征.单晶结构解析表明:两种配合物都属于单斜晶系,P21/c空间群.配合物Ⅰ的晶胞参数为:a=12.9541(2)A,b=5.54060(10)A,c=11.4288(2)A,β=106.3950(10)°.配合物Ⅱ的晶胞参数为:a=10.6619(3)A,b=8.6201(3)A,c=15.2628(4)A,β=102.286(2)°.在这两种结构中,硅酸钠均没有参与配位.

关 键 词:单晶  结构表征  铜配合物  晶系

Abstract:Two Cu( Ⅱ ) complexes with the ligand 8-Hydroxy quinoline have been synthesized and fully characterized by elemental analysis, IR, X-ray crystal diffraction, thermal analysis. Interestingly, different structures the two complexes synthesized have due to the different solvent, THF and methanol respectively. Single crystal X-ray diffraction analysis of the complexes Cu(C9 H6 NO)2 ( H2O)2 ] (complex Ⅰ, blue) and CU2 (C9 H6 HO)4 ] (complex Ⅱ, black) reveal their monomeric or dimeric nature. The two compounds both crystallize in the monoclinic system, space group P21/c. Complex( I ) has cell parameters a=12. 954 1(2)A, b=5. 5406 0(10),A, c=11. 428 8(2),A, β= 106. 395 0(10)°, and complex ( 11 ) with cell pa- rameters a=10. 661 9(3)A,b=8. 620 1(3)A,c= 15. 262 8(4)A,β=102. 286(2)°. In the two complexes, silicon do not participate in the coordination.
Keywords:single crystal  structure character  copper complex  lattice
