Bis(μ-di-phenyl-phosphan-yl)bis-[(tri-methyl-phosphane)cobalt(I)](Co-Co).
The title compound, [Co2{P(C6H5)2}2(C3H9P)4], was obtained by the addition of di-phenyl-phosphane to a solution of Co(CH3)(C3H9P)4. The dinuclear complex mol-ecule exhibits inversion symmetry with the inversion centre located between the two Co(I) atoms. The short Co-Co distance of 2.3670 (8) Å lies within the range of metal-metal double bonds. As a result of inversion symmetry, the four-membered Co2P2 core is rigorously planar, and the two bridging P(C6H5)2-ligands and the terminal C3H9P ligands are arranged in a pseudo-tetra-hedral fashion about the Co(I) atom.
