title: Kolbeckite, ScPO(4).2H(2)O, isomorphous with metavariscite.
abstract: This study presents the first structural report of kolbeckite, with the ideal formula ScPO(4).2H(2)O (scandium phosphate dihydrate), based on single-crystal X-ray diffraction data. Kolbeckite belongs to the metavariscite mineral group, in which each PO(4) tetrahedron shares four vertices with four ScO(4)(H(2)O)(2) octahedra and vice versa, forming a three-dimensional network of polyhedra.
