Oxidative additions of cyclo-octasulfur and cyclo-octaselenium to the cobalt(II) complex of 1,3-bis(dimethylphosphino)propane (dmpp): Crystal structures and spectroscopic properties of [Co(S2O)(dmpp)(2)]PF6 and [Co(Se-2)(dmpp)(2)]BF4
[Co(S2O-kappa(2)S and Se-2)(dmpp)(2)](+) complexes were prepared and characterized by X-ray analyses and UV-vis spectra to have side-on-bonded S2O2- and Se-2(2-) moieties. The analogous [Co(S2O-kappa(2)S)(depe)(2)](+) (depe = 1,2-bis(diethylphosphino)ethane) and [Co(Se)(dmpe)(2)](+) (dmpe = 1,2-bis(dimethylphosphino)ethane) complexes were also prepared.
