Mersalyl

Mersalyl (Mersal) is an organomercury compound[1] and mercurial diuretic. It is only rarely used as a drug, having been superseded by diuretic medications that do not contain mercury and are therefore less toxic. It features a Hg(II) centre. Mersalyl was originally adapted from calomel (Hg₂Cl₂), a diuretic discovered by Paracelsus.
