Khinite is a rare orthotellurate mineral with the formula Pb2+Cu2+3TeO6(OH)2. It crystallizes in the orthorhombic system and has a bottle-green colour. It is often found as dipyramidal, curved or corroded crystals no more than 0.15 mm in size. The tetragonal dimorph of khinite is called parakhinite.
