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.
