All regarded mercury compounds show certainly one of two optimistic oxidation states: I and II. Experiments have failed to unequivocally show any higher oxidation states: equally the claimed 1976 electrosynthesis of the unstable Hg(III) species and 2007 cryogenic isolation of HgF4 have disputed interpretations and continue to be difficult (if not extremely hard) to reproduce.[51]
Heating of mercury, or of compounds of mercury which will decompose when heated, should be performed with sufficient ventilation in order to attenuate exposure to mercury vapor. Quite possibly the most toxic types of mercury are its natural and organic compounds, such as dimethylmercury and methylmercury.
