Synthesis,Crystal Structure and Magnetic Properties of the Asymmetric Dinuclear Copper(Ⅱ) Macrocyclic Complex [Cu_2(C_(23)H_(26)Cl_2N_4O_2)](ClO_4)_2

大环双核铜(Ⅱ)配合物由N,N′-二甲基-N,N′-二(3-甲酰基-5-氯水杨醛)乙二胺和1,3-丙二胺,与铜(Ⅱ)反应形成的,经过X-射线单晶衍射结果表明:a=0.87105(16)nm,b=0.95778(18)nm,c=1.8104(3)nm,β=100.761(18)°,V=1.4838(5)nm3,Z=2,Dc=1.762Mg.m-3,μ=1.85 mm-1,F(000)=796,and final R1=0.061,wR2=0.126。晶体结构表明:两个铜离子位于双核大环中间,与大环的胺、亚胺以及酚羟基的氧进行配位。磁性结果表明配合物为反铁磁性。

The dinuclear copper（Ⅱ） macrocyclic complex has been synthesized by condensation between N,N′-dimethyl-N,N′-bis（3-formyl-5-chlorosalicylidene）ethylene diamine and 1,3-propanediamine in the presence of copper（Ⅱ）？ The complex was determined by X-ray diffractions single crystal structure analysis.The results indicates that the complex crystallizes in monoclinic,space group P21,Flack parameters（x） =0.06（2）,with a=0.871 05（16） nm,b=0.957 78（18） nm,c=1.810 4（3） nm,β=100.761（18）°,V=1.483 8（5） nm3,Z=2,Dc=1.762 Mg·m-3,μ=1.85 mm-1,F（000）=796,and final R1=0.061,wR2=0.126,The crystal structure shows that the two copper（Ⅱ） ions in the phenol-based macrocyclic dinuclear complex,are coordinated with（Namine）2O2 and（Nimine）2O2 sites.Magnetic measurements reveal an antiferromagentic interaction in the complex.CCDC： 624712.
