Four novel lanthanide complexes,[Ln(2,4-DClBA)3(terpy)(H2O)]·H2O (Ln= Eu(1),Tb(2)); [Ln(2,4-DClBA)3(5,5-DM-2,2-bipy)(C2H5OH)]2 (Ln = Eu(3),Tb(4); 2,4-DClBA: 2,4-dichlorobenzoate; terpy: 2,2:6,2-terpyridine; 5,5-DM-2,2-bipy:5,5-Dimethyl-2,2-bipyridine) have been synthesized via conventional solution method at room temperature and structurally characterized by single crystal and powder X-ray diffraction.Complexes 1-2 exhibit the mononuclear lanthanide architectures and each Ln3+ ion is nine-coordinated adopting a distorted monocapped square antiprismatic molecular geometry,while the complexes 3-4 exhibit the binuclear lanthanide architectures in which each Ln3+ ion is eight-coordinated adopting a distorted square antiprismatic molecular.
