The structure described by CoAl(WO4)2 is Hydrophilite-derived structured and crystallizes in the triclinic P-1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(2), one O(6), two equivalent O(3), and two equivalent O(8) atoms to form 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 44-58°. In the second W site, W(2) is bonded to one O(1), one O(5), two equivalent O(4), and two equivalent O(7) 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(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-55°. Co(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form CoO6 octahedra that share corners with four equivalent W(1)O6 octahedra, corners with four equivalent W(2)O6 octahedra, and edges with two equivalent Al(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-58°. Al(1) is bonded to one O(1), one O(2), one O(5), one O(6), one O(7), and one O(8) atom to form AlO6 octahedra that share corners with four equivalent W(1)O6 octahedra, corners with four equivalent W(2)O6 octahedra, and edges with two equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-53°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one W(2), one Co(1), and one Al(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one W(1), one Co(1), and one Al(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to two equivalent W(1) and one Co(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to two equivalent W(2) and one Co(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one W(2), one Co(1), and one Al(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to one W(1), one Co(1), and one Al(1) atom. In the seventh O site, O(7) is bonded in a trigonal planar geometry to two equivalent W(2) and one Al(1) atom. In the eighth O site, O(8) is bonded in a distorted trigonal planar geometry to two equivalent W(1) and one Al(1) atom. is represented by the CIF card [CIF]
