摘要: 基于构筑单元K[Cr(bpb)(CN)2]和[Cu(cyclam)](ClO4)合成了一个氰根桥联的CrⅢ-CuⅡ一维化合物{[Cu(cyclam)][Cr(bpb)(CN)2]2·2H2O}n[cyclam=1,4,8,11-四氮杂环十四烷;bpb2-=1,2-二（2-吡啶甲酰胺基）苯](1), 并通过X-衍射单晶分析表征其结构特征。结果表明：化合物1是由氰根桥联的2种不同金属组成的聚合物, 其结构属于三斜晶系, P1 空间群, a=0.9667 3(19) nm, b=1.345 1(3) nm, c=1.382 0(3) nm, α=77.12(3)°, β=76.93(3)°, γ=82.02(3)°, V=1.699 1(6) nm3, Z=2, Dc=1.567 g·cm-3, μ=1.086 mm-1, F(000)=828, R1=0.0413, wR2=0.1200。磁性研究表明：配合物11中的CrⅢ离子和CuⅡ离子之间存在弱的铁磁耦合作用。
