The action of two equivalents of 1,2-bis(diphenylphosphino)-4-tert-butylcyclopentadienyllithium on FeCl 2 led to the corresponding 1,1',2,2'-tetraphosphinoferrocene. The X-ray structure of this bulky ferrocene is described. The spectroscopic results reveal a conformational chirality with a cisoid disposition of the phosphino groups. The first results about the complexation with representative elements of Group IX and X (Rh, Pd, Ir) are reported.
