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 novel 3d-4f heterometallic complexes were designed and synthesized with [(bpca) Fe (CN) 3] - (bpca = bis (2-pyridylcarbonyl) amide) Fe (CN) 3Pr (H2O) 5] Cl2} n (1) and {[(bpca) 2Fe2 (CN) 6Pr (H2O) 6] Cl.4H2O} n (2) were synthesized and their crystal structures were determined. The crystal of compound 1 belongs to orthorhombic system, Pnma space group, and compound 2 belongs to triclinic system, space group P1. Among the two compounds, [(bpca) Fe (CN) 3] - and [Pr (H2O) x] 3+ (1, x = 5; 2, x = 6) are alternately arranged to form one- The three-dimensional network structure is formed by π-π stacking, hydrogen bonding and intermolecular short distance interaction.
