The structure of , dppe = bis(diphenylphosphino)ethane, obtained by a new and potentially general synthesis, is essentially planar with only a 3 deg twist between the two PdP2 planes and a P-P bond distance of 2.121(4) Angstrom; 31P n.m.r. data on the analogous platinum complexes show very small s-character in the Pt-P(diphosphene) bonds, suggesting that the structure is essentially a diphosphene bound to Pt⁰ rather than that of a diphosphido(2-) ligand bound to Pt^II.
