Notes:
The title compound, [Co2(C25H22P2)(C8H18Sn2)(CO)4], was prepared by displacement of two molecules of carbon monoxide in hexacarbonyldicobalt[μ,η2-bis-(trimethylstannyl)]acetylene with a bidentate bis(diphenylphosphino)methane ligand. The displacement of carbon monoxide yields the product with substantially increased thermal stability and brings about noticeable changes in the geometry of the dicobaltatetrahedrane moiety, viz. lengthening of the carbon–carbon bond and shortening of the cobalt–cobalt and cobalt–carbon bonds.
