Dichloro[1,2-bis(diphenylphosphino)ethane]nickel is a coordination complex with the formula NiCl2(dppe); where dppe is the diphosphine 1,2-bis(diphenylphosphino)ethane. It is used as a reagent and as a catalyst. The compound is a bright orange-red diamagnetic solid. The complex adopts a square planar geometry.
It is prepared by combining equimolar portions of nickel(II) chloride hexahydrate with dppe: Ni(H2O)6Cl2 + dppe → NiCl2(dppe) + 6 H2O
