Cationic tetracoordinate nickel(II) compounds containing a nickel-carbon ? bond with general formula Y, (etp = bis(2-diphenylphosphinoethyl)phenylphosphine, PhP(CH2CH2PPh2)2; R = CH3, CH2C6H5, C6H5; Y = BPh4, PF6) were synthesized by reaction of the complexes Y (X = halogen) with appropriate Grignard reagents.This type of organometallic complexes undergo insertion of sulfur dioxide into the Ni-C bond with formation of tetracoordinate O-sulfinate derivatives of nickel(II).The structure of BPh4 has been determined from three dimensional X-ray data collected by counter methods.The compound crystallized in the triclinic group P with cell dimensions a 16.726(4), b 15.350(4), c 11.632(3) Angstroem, α 66.55(4), β 73.37(4), γ 74.75(4) deg, Z = 2.The structure was refined by full matrix least-squares methods to a conventional R factor of 0.076.The coordination polyhedron has a distorted square planar geometry.The sulfinate group is linked to the metal through an oxygen atom.
