The material structure described by CoBi6P2(O7F)2 crystallizes in the monoclinic C2/c space group. Co(1) is bonded to two equivalent O(1), two equivalent O(4), and two equivalent O(5) atoms to form CoO6 octahedra that share corners with four equivalent P(1)O3F tetrahedra. There are three inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 4-coordinate geometry to one O(2), one O(3), one O(7), and one O(8) atom.
