The crystal structures of *H2O (1) and *H2O (2) where bipyam-H = bis(2-pyridyl)amide, have been determined by X-ray analysis, in the orthorhombic space group Pnn2: (1), a=14.092(3), b=12.895(3), c=11.190(2) Angstroem, Z=2, and R=0.032 for 2453 observed and 2029 unique reflections; (2), a=14.186(3), b=13.040(3), c=11.313(2) Angstroem, Z=2, and R=0.043 for 1574 observed and 1465 unique reflections.The two structures are isomorphous with near isostructural units in special positions of two-fold symmetry and a non-co-ordinated water molecule.The Cu3N12X2 chromophores involve nearly linear Cu3 units, Cu-Cu-Cu 178.4 deg (mean), terminated by the two halide anions.The four separate bipyam-H ligands act as tridentate ligands, involving co-ordination to the three separate copper(II) ions, with Cu-Cu distances of 2.471(1) and 2.468(1) Angstroem, for (1) and (2), respectively.If the Cu-Cu separations are ignored, the central Cu atom in both structures involves a four-co-ordinate rhombic coplanar CuN4 chromophore generated by the central amido nitrogens of the four bipyam-H ligands.The two terminal Cu atoms involve a square-based pyramidal CuN4X chromophore, generated by the terminal pyridine nitrogens of the four bipyam-H ligands and an axial halide anion.An average dihedral angle of 48 deg is involved between the planes of the pyridine rings of the individual bipyam-H ligands, which results in a spiral configuration of the units.The spin-only magnetic moment of the complex (1) is ca. 1.40 B.M. per Cu atom, consistent with antiferromagnetic coupling between the copper(II) atoms of the trimer.Both complexes are e.s.r. silent, again consisitent with strong antiferromagnetic coupling.The electronic spectra of (1) and (2) have a band maximum at 15500 cm-1, with a high-energy shoulder at 19230 cm-1, consistent with the two different stereochemistries present.

The development of a new glycosylation method for efficient stereoselective synthesis of beta-gluco- and galactosides from their corresponding armed trichloroacetimidate donors mediated by 10 mole% of FeCl3 has been focused. FeCl3 has also been applied to a number of glucose, galactose, mannose and rhamnose based trichloroacetimidate donors with various protecting groups incorporated at the C-2-position to prepare a variety of disaccharides and trisaccharides with excellent 1,2-trans selectivity. FeCl3 can also modulate the 1,2-trans selectivity of the reaction of 2-O-alkylated gluco- and galacto-pyranosyl trichloroacetimidates with phenolic compounds leading to the generation of the corresponding beta-O-aryl glycosides in excellent yield and selectivity. Apart from these the present methodology has been successfully utilized for double glycosylation and orthogonal glycosylation reactions along with its application in one-pot three component orthogonal glycosylation reactions for synthesis of a trisaccharide.
