The structure described by CoAl(WO4)2 crystallizes in the triclinic P1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(7), and one O(8) atom to form distorted WO6 octahedra that share corners with three equivalent Al(1)O5 trigonal bipyramids and edges with two equivalent W(2)O6 pentagonal pyramids. In the second W site, W(2) is bonded to one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom to form distorted WO6 pentagonal pyramids that share corners with three equivalent Al(1)O5 trigonal bipyramids and edges with two equivalent W(1)O6 octahedra. Co(1) is bonded in a 4-coordinate geometry to one O(2), one O(3), one O(4), one O(7), and one O(8) atom. Al(1) is bonded to one O(1), one O(2), one O(4), one O(5), and one O(6) atom to form AlO5 trigonal bipyramids that share corners with three equivalent W(1)O6 octahedra and corners with three equivalent W(2)O6 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 25-59°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one W(1) and one Al(1) atom. In the second O site, O(2) is bonded in a 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 distorted T-shaped geometry to one W(1), one W(2), and one Co(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one W(1), one W(2), one Co(1), and one Al(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one W(2) and one Al(1) atom. In the sixth O site, O(6) is bonded in a distorted bent 120 degrees geometry to one W(2) and one Al(1) atom. In the seventh O site, O(7) is bonded in a distorted trigonal non-coplanar geometry to one W(1), one W(2), and one Co(1) atom. In the eighth O site, O(8) is bonded in a trigonal non-coplanar geometry to one W(1), one W(2), and one Co(1) atom. is represented by the CIF file [CIF]
