New Pb-Pb bonds: syntheses and molecular structures of hexabiphenyldiplumbane and tri(trisbiphenylplumbyl)plumbate

Reaction of lead(II) chloride with biphenylmagnesium bromide yields Bp(3)Pb-PbBp(3) and [(THF)(3)Mg(mu-Cl)(3)Mg(THF)(3)]-[Pb(PbBp(3))(3)] (Bp = biphenyl), which, upon single crystal X-ray crystallographic analysis, reveals an interesting variation of Pb-Pb bond distances.
