摘　　要：室温下,通过溶剂挥发法合成了对氯苯乙酸邻菲啰啉铜(Ⅱ)配合物(C_(28)H_(20)Cl_(2)CuN_(2)O_(4))和对氯苯乙酸2,2′-联吡啶铜(Ⅱ)配合物(C_(26)H_(22)Cl_(2)CuN_(2)O_(5))。用X-射线单晶衍射测定了配合物的晶体结构;结果显示配合物C_(28)H_(20)Cl_(2)CuN_(2)O_(4)属于三斜晶系,P1空间群,每个不对称单元由1个铜(Ⅱ)离子、2个对氯苯乙酸配体及1个邻菲啰啉配体组成。配合物C_(26)H_(22)Cl_(2)CuN_(2)O_(5)属于单斜晶系,P2_(1)/n空间群;每个不对称单元由1个铜(Ⅱ)离子、2个对氯苯乙酸配体及1个2,2′-联吡啶配体组成。在荧光光谱上,配合物C_(28)H_(20)Cl_(2)CuN_(2)O_(4)的最强激发峰和发射峰分别在380 nm和430 nm处,配合物C_(26)H_(22)Cl_(2)CuN_(2)O_(5)的最强激发峰和发射峰分别在380 nm和430 nm处;两个配合物在室温下稳定。The copper(Ⅱ)complex[C_(28)H_(20)Cl_(2)CuN_(2)O_(4)](4-chlorophenylacetic acid,1,10-phenanthroline)and complex[C_(26)H_(22)Cl_(2)CuN_(2)O_(5)](4-chlorophenylacetic acid,2,2′-bipyridine)were synthesized via solvent evaporation method.Their crystal structures were determined by the crystal X-ray diffraction method.The results showed that complex[C_(28)H_(2)0 Cl_(2)CuN_(2)O_(4)]crystallized in the triclinic space group P1 with each asymmetric unit consisting of one Cu(Ⅱ)ions,two 4-chlorophenylacetic acid ligands,and one 1,10-phenanthroline ligand.Complex[C_(26)H_(22)Cl_(2)CuN_(2)O_(5)]crystallized in the monoclinic with space group P2_(1)/n with each asymmetric unit consisting of one Cu(Ⅱ)ions,two 4-chlorophenylacetic acid ligands,and one 2,2′-bipyridine ligands.The excitation peak of complex[C_(28)H_(2)0 Cl_(2)CuN_(2)O_(4)]was 380 nm.The emission peak was 430 nm,the excitation peak of complex C_(26)H_(22)Cl_(2)CuN_(2)O_(5)was 380 nm,and the emission peak was 430 nm.Two complexes were stable at room temperature.
