Several novel mixed ligand lanthanum complexes with 1,10-phenantroline and phenylcyanamide derivatives with the formula of [La(phen)3Cl3·OH2] (1) and [La(phen)3L3] (phen = 1,10-phenantroline; L = 2-clorophenylcyanamide (2), 2,5-dichlorophenylcyanamide (3), 2,4-dichlorophenycyanamide (4) and 2,4,5-trichorophenycyanamide (5)) are successfully synthesized in aqueous solution. The complexes are characterized by spectroscopic analysis such as infrared, 1H NMR, UV–Vis spectroscopy as well as elemental analysis. The molecular structure of 3 is determined by single-crystal X-ray diffraction method. Three 2,5-Cl2pcyd and three phenanthroline ligands are coordinated to the central La atom in monodentate and bidentate manner, respectively.
