Organomercury compounds. XI. Some coordination derivatives of bispentafluorophenylmercury

Abstract

The complexes (C₆F₅)₂HgL (L = 4,4?-dimethyl-2,2?-bipyridyl, 2,2?- biquinolyl, 2,2?:6?,2?-terpyridyl, 2,4,7,9,-tetramethyl-1,10- phenanthroline, ethylenediamine, o-phenylenediamine, diphenylamine, pyridine, 4-cyanopyridine, triphenylphosphine, triphenylphosphine oxide, or 1,2-bisdiphenylarsinoethane), (C₆F₅)₂HgL₂ (L = di-2- pyridylamine), and [(C₆F₅)₂Hg]₂L (L = bisdiphenylphosphinomethane or bisdiphenyl-arsinomethane) have been prepared, and their constitution, solution stabilities, and structures studied, together with those of the known complexes (C₆F₅)₂HgL (L = 2,2?- bipyridyl, 1,10-phenanthroline, or 1,2-bisdiphenylphosphinoethane). Coordination of triphenylarsine oxide to bispentafluorophenylmercury in solution has also been detected, but the complex could not be isolated.
