Methyl- and phenyl-mercury(II) ions reacted, in the molar ratio 2:1, with bidentate phosphines L-L to give binuclear complexes of general formula [RHg(L-L)HgR]2+ . [L-L = Ph2P(CH2)nPPh2, n = 1-3]. When an excess of the phosphine ligand is present an intermolecular exchange process occurs which leads to the formation of the symmetrically substituted compounds, HgR2 and [Hg(L-L)2]2+. The reactions in solution have been studied by multinuclear NMR spectroscopy; the structure of the bimetallic species was deduced with the aid of computer simulation. The single-crystal structure of [Hg(Ph2PCH2CH2PPh2) 2][O3SCF3]2 [orthorhombic, space group Pbcn, a = 17.141(3), b = 20.158(3), c = 15.614(9) A, Z = 4] showed the mercury atom to be in a distorted-tetrahedral configuration.
