Unexpected oxidation of a diphosphine by bis(1,3-diphenylpropane-1,3-dionato)cobalt(II), [Co(dbm)2].
The reaction of bis(1,3-diphenylpropane-1,3-dionato)cobalt(II), [Co(dbm)(2)], with bis(diphenylphosphino)ethane (dppe) affords the coordination polymer catena-poly[[bis(1,3-diphenylpropane-1,3-dionato-kappa(2)O,O')cobalt(II)]-mu-ethylenebis(diphenylphosphine oxide)-kappa(2)O:O'], trans-[Co(C(15)H(11)O(2))(2)(C(26)H(24)O(2)P(2))](n), as a result of oxidation of the diphosphine. The Co atom is octahedral, with a CoO(6) coordination sphere, and the chelating dbm ligands adopt a trans configuration. The Co atom also lies on a centre of inversion, with a further symmetry centre bisecting the bridging ethylenebis(diphenylphosphine oxide) ligand.
