Two new complexes [Cu(N,N0,N00-(D-Glc)3-tren)Cl]Cl (1) and [Cu(N,N0,N00-(maltose)-tren)] Cl2ÆH2O (2), have been synthesized and characterized by elementary analysis, and the IR and UV spectra suggest that complex 1 and complex 2 are arranged in trigonal bipyramidal configuration and square-pyramidal configuration, respectively. The crystal structure of complex 1 has been determined by X-ray diraction as: a% 9: 3476ð8Þ, b% 17: 4236ð13Þ, c% 9: 7836ð8Þ A, b% 91: 197ð3Þ, V% 1593: 1ð2Þ A3, Z% 2, and R% 0: 0325, which shows that three secondary amine groups (N-1, N-2, N-3) of the glycosylamine ligand forms the equatorial plane, and the tertiary amine (N-4) and one Cl are located at the apical positions.
