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.
