Organomercury compounds:XI. Some coordination derivatives of bispentafluorophenylmercury

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.
