Copper(II) borate is an inorganic compound with the formula Cu3(BO3)2. It consists of copper atoms in their cupric oxidation state and orthoborate groups. In the 19th century it was proposed to be used as a green pigment to replace the very toxic paris green.[3] It has been studied for its photocatalytic properties.[2]
