Reaction of hexanuclear octahedral molecular precursors with a 3-chlorobenzoate ligand affords an unprecedented family of isostructural polylanthanide complexes via solvothermal and microwave-assisted syntheses in an acetonitrile medium. The general chemical formula of the compounds that constitute this series is {[Ln63-OH)2(H2O)2(NO3)2(3-cb)14]·(CH3CN)4}, where 3-cb stands for 3-chlorobenzoate and Ln = Eu, Tb, Dy, Ho, Er, or Y. The crystal structure, solubility, and magnetic and luminescent properties of these complexes have been studied. The luminescent properties evidence that the composition of the hexalanthanide precursor is preserved during the synthetic process that is of particular interest for cases in which heterolanthanide complexes are targeted.

六亚铁配合物作为分子前体:合成,晶体结构以及发光和磁性。

六核八面体分子前体与3-氯苯甲酸酯配体的反应通过溶剂热和微波辅助合成在乙腈介质中提供了前所未有的同结构聚镧系元素配合物。构成该系列的化合物的化学通式为{[LN 6(μ 3 -OH)2(H 2 O)2(NO 323-CB14 ]·(CH 3 CN)4 },其中,3-CB -代表3-氯苯甲酸酯,Ln = Eu,Tb,Dy,Ho,Er或Y。已经研究了这些配合物的晶体结构,溶解度以及磁和发光性质。发光性质证明六镧系元素前体的组成在合成过程中得以保留,这对于杂镧系元素络合物靶向的情况尤为重要。
