Synthesis and characterization of Cr(III), Mn(II), Co(II), Ni(II), and Cu(II) complexes with a hexadentate hemi-cage ligand formed with bipyridine
by Williams, A. L.; Bhuiyan, A. A.; Turner, M. O.; Millett, F.; Durham, B.
A series of transition metal complexes, Cr(III), Mn(II), Co(II), Ni(II), and Cu(II), have been prepared and characterized using the hemi-cage ligand previously reported by Beeston et al. [R.F. Beeston, W.S. Aldridge, J.A. Treadway, M.C. Fitzgerald, B.A. Degraff, S.E. Stitzel. Inorg. Chem., 37, 4368 (1998)]. The ligand is composed of three bipyridyl groups covalently bound to a central benzene ring through ethyl groups. Preliminary DFT calculation with Cr(III) indicates that the ligand will allow the three bipyridyl groups to coordinate to a metal with a pseudooctahedral coordination geometry. Comparison of UV-Vis spectra, magnetic susceptibility, and cyclic voltammetry indicates that the complexes are remarkably similar to the corresponding bipyridine complexes, [image omitted]. No evidence was found to indicate that the ligand restricts the motion of the bipyridyl groups enough to change the chemical properties.
