In chemistry, a lyate ion is the anion derived by the deprotonation of a solvent molecule. For example, a hydroxide ion is formed from the deprotonation of water and methoxide (CH3O−) is the anion formed by the deprotonation of methanol. See also lyonium ion which is the cation formed by the protonation of a solvent molecule.
