Syntheses and Crystal Structures of Two One-dimensional 3d-4f Heterobimetallic Complexes Based on [Fe(bpca)(CN)_3]^-

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 stack-ing interactions,hydrogen bonds and short-distance intermolecular interactions.
