以[(bpca)Fe(CN)3]-(bpca=二(2-吡啶羰基)酰胺阴离子)为构筑基元,设计合成了2个新颖的3d-4f异金属配合物,{[(bpca)Fe(CN)3Pr(H2O)5]Cl2}n(1)和{[(bpca)2Fe2(CN)6Pr(H2O)6]Cl·4H2O}n(2),并测定了它们的晶体结构.化合物1的晶体属正交晶系,Pnma空间群;而化合物2属三斜晶系,P1空间群.在这2个化合物中,[(bpca)Fe(CN)3]-和[Pr(H2O)x]3+(1,x=5;2,x=6)交替排列形成一维链状结构,并通过π-π堆积作用、氢键作用及分子间短距离相互作用形成三维网络结构.

Two 3d-4f bimetallic complexes, {[(bpca)Fe(CN)3Pr(H2O)5]Cl2}n (1) and {[(bpca)2Fe2(CN)6Pr(H2O)6]Cl· 4H2O}n (2) (bpca=bis(2-pyridylcarbonyl)amidate anion), have been synthesized and their crystal structures were dete- rmined. Complex 1 crystallizes in the orthorhombic space group Pnma while complex 2 is in the triclinic space group P1. Both complexes possess novel one-dimensional (1D) chain structures with alternating arrays of [(bpca)Fe(CN)3]- and [Pr(H2O)x]3+ (x=5 for 1 and 6 for 2) fragments. They exhibit 3D supramolecular architectures through π-π stacking interactions, hydrogen bonds and short-distance intermolecular interactions. CCDC: 624698, 1; 624699, 2.
