摘要：大环双核铜髤配合物由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，与铜髤反应形成的，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=1.762·m-3，μ=1.85mm-1，F(000)=796，andfinalR1=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Mg

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。关键词：晶体结构；双核铜配合物；磁性中图分类号：O614.121
