All regarded mercury compounds exhibit certainly one of two optimistic oxidation states: I and II. Experiments have failed to unequivocally demonstrate any greater oxidation states: the two the claimed 1976 electrosynthesis of an unstable Hg(III) species and 2007 cryogenic isolation of HgF4 have disputed interpretations and continue to be tricky (if not not possible) to reproduce.[fifty seven]
