| Abstract: | The new vanadium(II) complexes [V(opd)4]X2 and [V(mopd)4]X2, where opd = o-phenylenediamine, mopd = 4-methyl-o-phenylenediamine, and X = Cl or Br, have been prepared by reaction of the aromatic diamine with the vanadium(II) halide in EtOH. Magnetic measurements suggest that these contain octahedral vanadium(II) complex cations, and this is confirmed by the diffuse reflectance spectra. I.r. spectra suggest that the [V(opd)4]2+ cations contain two bidentate and two monodentate diamine ligands. |
