Abstract
The reaction between Co(II) and the deprotonated tetraphenylimidodiphosphinic acid, [(OPPh2)(2)N](-), afforded a binuclear [Co-2{(OPPh2)(2)N}(4)] complex, as revealed by X-ray crystallography. The structure contains two monometallic biconnective I(OPPh2)2N]- ligands, with an averaged Co-O bond length of 2.008 angstrom. The other two [(OPPh2)(2)N](-) act as bimetallic triconnective ligands, forming two oxygen atom bridges, with the four Co-O(bridging) distances averaged at 2.155 angstrom, and the two Co-O(non-bridging) distances at 1.973 angstrom. The two approximately trigonal bipyramidal Co(II) ions are at a Co center dot center dot center dot Co distance of 3.301 angstrom. The analysis of the magnetic properties of [Co-2{(OPPh2)(2)N}(4)] is consistent with an unusual ferromagnetic interaction, in a binuclear Co(II) system, between the two S = 3/2 Co(II) ions.
