| Abstract: | New 2-hydroxynaphthalene-1-carboxaldehyde (Hhnca) complexes M(hnca)3 (M = Cr, Fe,Ru or Rh), M(hnca)2 (M=Co, Ni,Cu or Pd),trans-MO2(hnca)2(M = Os, U), [Ag(hnca)2]-, ReO(PPh3)(hnca)2I, [Cu(py)2(hnca)]+, [Ni(bipy)2(hnca)]+ and [CoL2(hnca)]+ (L=bipy or py2) are described. Their i.r., Raman, 1H-n.m.r. and electronic spectra and magnetic moments have been measured and are discussed. The proton–ligand formation constant (pK*_A) of the ligand has been determined potentiometrically. |
