The compound described by CoAl(WO4)2 is Hydrophilite-derived structured and crystallizes in the monoclinic P2/c space group. W(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form distorted WO6 octahedra that share corners with four equivalent Co(1)O6 octahedra, corners with four equivalent Al(1)O6 octahedra, and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-57°. Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CoO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Al(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-57°. Al(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form AlO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-53°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one W(1), one Co(1), and one Al(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent W(1) and one Co(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one W(1), one Co(1), and one Al(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to two equivalent W(1) and one Al(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
