5-溴-2-羟基苯基甲基酮对甲氧基苯甲酰腙铜(Ⅱ)配合物的合成及其晶体结构

摘要

A novel ligand, 5-bromo-2-hydroxyphenyl methyl ketone p-methoxy benzoyl hydrazone (LH), was synthesized by condensation reaction of 5-bromo-2-hydroxyphenyl methyl ketone with p-methoxy benzoyl hydrazine. Copper( Ⅱ) complex with L and pyridine, CuLPy, was prepared by hy-drothermal synthesis at 120 ℃ from LH and pyridine solution of CuCl2 in methanol. The structure was characterized by XRD, IR and elemental analysis. CuLPy belongs to monoclinic crystal system, space group C2/c with a=2.0904(18) nm, 6 = 1.348 0(12) nm, c = 1.473 3(14) nm, β= 104. 584 (2)°, V=4.017 9(6) nm3, Z = 8, Dc = 1.669g- cm-3.%5-溴-2-羟基苯基甲基酮与对甲氧基苯甲酰肼缩合制得新型配体5-溴-2-羟基苯基甲基酮对甲氧基苯甲酰腙(LH);LH与氯化铜的吡啶溶液在甲醇中于120℃通过水热合成制得铜(Ⅱ)配合物(CuLPy),其结构经XRD,IR和元素分析表征.CuLPy属单斜晶系,空间群C2/c,晶胞参数a=2.090 4(18) nm,b=1.348 0(12)nm,c=1.473 3(14) nm,β=104.584(2)°,V=4.017 9(6) nm3,Z=8,Dc= 1.669 g.cm -3.
