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)).
