STRUCTURES OF MIXED BENZENETHIOLATO PHOSPHINO DINUCLEAR COMPLEXES OF NICKEL(II) AND PALLADIUM(II)

The structures of bis{[1,2-bis-(diphenylphosphino)ethane]nickel(II)} p erchlorate acetonitrile solvate, [Ni2(SPh)2(dppe)2]-(ClO4)2.2MeCN (1), and benzenethiolato)(triphenylphosphino)palladium(II)] acetonitrile s olvate, [Pd2(SPh)4(PPh3)2].MeCN (2), have been determined by X-ray dif fraction. The dinuclear [Ni2(SPh)2(dppe)2]2+ cation is crystallographi cally centrosymmetric about the midpoint of Ni ... Ni' and is formed b y the edge sharing of two square-planar NiP2S2 Coordinations. The dinu clear [Pd2(SPh)4(PPh3)2] MolecUle is located on a crystallographic inv ersion centre at (0,0,0) and comprises two PdPS3 coordination planes s haring two mu-SPh ligands.
