1,2-Bis(dimethylphosphino)ethane (dmpe) is a diphosphine ligand in coordination chemistry. It is a colorless, air-sensitive liquid that is soluble in organic solvents. With the formula (CH2PMe2)2, dmpe is used as a compact strongly basic spectator ligand (Me = methyl), Representative complexes include V(dmpe)2(BH4)2, Mn(dmpe)2(AlH4)2, Tc(dmpe)2(CO)2Cl, and Ni(dmpe)Cl2.[2]
