摘要: The preparation and characterization of praseodymium(III) neodymium(III) complexes heptadentate (N4O3) ligand trensal, tris[2-(salicylideneamino)ethyl]amine (H3L1), have been studied. These (PrL1 NdL1) were prepared by the reaction or complex 1,9-bis(2-aminoethyl)-1,4,6,9,12,14-hexaazacyclohexadecane with salicylaldehyde in acetonitrile. Alternatively, tris(2-aminoethyl)amine presence salt acetonitrile also gave trensal. molecular structures PrL1 NdL1 determined X-ray structural analysis; these are rare examples lanthanide which metal ions coordinated four nitrogen atoms three oxygen atoms. crystals Pr(C27H27N4O3)·0.5CH3CN Nd(C27H27N4O3)·0.5CH3CN both trigonal, space group , a = 13.713(2), c 8.093(3) A, U 1318.0(7) A3, Z ...
