| 摘要: 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。 |

| Abstract: 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 stack-ing interactions, hydrogen bonds and short-distance intermolecular interactions. CCDC: 624698, 1; 624699, 2. |
