The behaviour of O-alkyl dithiocarbonato complexes, , towards several phosphines has been studied.Depending on the S2COR derivative and phosphine (L) used, octahedral complexes , paramagnetic five-co-ordinate complexes , and square-planar (R=Et or cyclo-C6H11) and complexes have been obtained.The reaction of (R=Me, Et, or cyclo-C6H11) with an excess of dppe gives which is the first Ni^II-dithiocarbonate complex described.This compound reacts with MeI and C3H5Br to give (X=I or Br).There is no reaction with Lewis-base N donors or with carbon monoxide.
