Kainotropite is a rare vanadate mineral with the formula Cu₄FeO₂(V₂O₇)(VO₄). It contains trivalent iron. It is one of many fumarolic minerals discovered on the Tolbachik volcano. The name of its parental fumarole is "Yadovitaya", which means poisonous.^{[2] [3]}

Relation to other minerals

Structure of kainotropite is unique. However, there are other minerals containing both copper and divanadate group, like engelhauptite and volborthite.^{[4] [5]}
