Abstract

The use of dicyanamide and chelating phenanthroline ligands resulted in the synthesis of organometallic europium and neodymium coordination polymers [Ln(Phen)2{N(CN)2}3–xClx(CH3OH)](CH3OH)y] (Ln = Eu (I), Nd (II)) in which the dicyanamide ligand forms 1D chains, while the phenanthroline ligand provides packing of the 1D polymer in the crystal lattice. Under similar conditions, the binuclear complex [Gd(Phen)2(μ-OH){N(CN)2}(H2O)]2Cl2 (III) was obtained for gadolinium, with the dicyanamide ligands being coordinated to only one gadolinium ion without forming a polymer chain (CCDC CIF files nos. 1936378 (I), 1936379 (II), 1936377 (III)).

基于双氰胺配体的镧系配位聚合物

摘要

使用双氰胺和螯合菲咯啉配体可合成有机金属euro和钕配位聚合物[Ln(Phen)2 {N(CN)2 } 3– x Cl x(CH 3 OH)](CH 3 OH)y ] (Ln = Eu(I),Nd(II)),其中双氰胺配体形成1D链,而菲咯啉配体则将1D聚合物堆积在晶格中。在类似条件下,双核络合物[Gd(Phen)2(μ-OH){N(CN)2 }(H 2 O)] 2 Cl 2对于for,获得了III),其中双氰胺配体仅与一个ion离子配位而没有形成聚合物链(CCDC CIF文件号1936378(I),1936379(II),1936377(III))。
