Metal-N-saccharide chemistry: synthesis and structure determination of two Cu(II) complexes containing glycosylamines.
Two new complexes [Cu(N,N',N"-(D-Glc)3-tren)Cl]Cl (1) and [Cu(N,N',N"-(maltose)-tren)]Cl2.H2O (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 diffraction as: a = 9.3476(8), b = 17.4236(13), c = 9.7836(8) angstroms, beta = 91.197 degrees, and V = 1593.1(2) Angstroms3, 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.
