Abstract
Reaction of halogenomagnesium derivatives of decaborane(14), B10H13MgX, (X = Br, l), with alkylmercury(II) halides, RHgY, (R = Me; Y = Cl, Br, l: R = Et, Prn; Y = Cl), in ether solvents, yields the solvated double salts of magnesium, (MgY2)x{Mg[Hg(B10H12)2]}(solvent)y, which dissolve in water to form the ion, [Hg(B10H12)2]2–, a formal mercury(II) complex of the dodecahydro-nido-decaborate(2-) ion, B10H12 2–. Physical data (including 28·87 MHz and 80·53 MHz 11B n.m.r. spectra) for tetramethylammonium and triphenylmethylphosphonium salts of the anions, [Zn(B10H12)2]2–, [Cd(B10H12)2]2–, and [Hg(B10H12)2]2– are presented and correlated with their known structures in the solid state.Keywords
