  Synthetic and Spectroscopic Studies of Xanthato-Bridged Heterobimetallic Complexes Containing Diamagnetic and Paramagnetic Metal Ions

  摘要：

  A series of heterobimetallic complexes of the form M[M′(Etxant)3] and M[M′(Etxant)3]2 have been prepared by the reaction of K[M′(Etxant)3] [M′=Ni(II), Cd(II), or Pb(II)] and metal nitrate or sulfate [Ma=Co(II), Ni(II), Cd(II), Tl(I), Pb(II), or Ag(I), Etxant=ethylxanthate]. These complexes have been characterized by elemental analysis, molecular weight, molar conductance, magnetic susceptibility, (1H, 13C) NMR, electronic, and infrared spectral studies. Magnetic moment and electronic spectral data indicate square planar geometry around Co(II) or Ni(II), except Tl[Ni(Etxant)3] in which Ni(II) is octahedrally coordinated. NMR spectra of M[M′(Etxant)3]2 clearly indicate the presence of two different ethylxanthate moieties, one attached to the diamagnetic Ni(II), Cd(II), or Pb(II) and the other to the paramagnetic Co(II) centre. Electrical conductance values indicate their nonelectrolytic behavior. Interaction of heterobimetallic complexes with different solvent have been studied and solvent characteristics (donor number, dielectric constant, EB (electrovalent) and CB (covalent) parameters) have been related to the structural properties of the complexes. On the basis of these studies, monomeric structure for M[M′(Etxant)3]2 and polymeric structure for M[M′(Etxant)3] have been suggested.
