Ilyukhinite is a very rare mineral of the eudialyte group,[2] with formula (H3O,Na)14Ca6Mn2Zr3Si26O72(OH)2·3H2O.[4] The formula given is simplified and does not show the presence of cyclic silicate groups. Ilyukhinite is the second group representative with species-defining hydronium ion after aqualite.[2]
