The crystal structure described by K2W2O5 crystallizes in the triclinic P-1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a distorted linear geometry to one O(2), one O(6), two equivalent O(3), and two equivalent O(4) atoms. In the second K site, K(2) is bonded in a distorted single-bond geometry to one O(2), two equivalent O(3), and two equivalent O(4) atoms. There are three inequivalent W sites. In the first W site, W(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second W site, W(2) is bonded in a square co-planar geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. In the third W site, W(3) is bonded in a distorted L-shaped geometry to one O(3), one O(5), one O(6), and two equivalent O(4) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one W(1) and one W(2) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one K(1), one K(2), one W(1), and one W(2) atom. In the third O site, O(3) is bonded in a 7-coordinate geometry to two equivalent K(1), two equivalent K(2), one W(2), one W(3), and one O(5) atom. In the fourth O site, O(4) is bonded in a 6-coordinate geometry to two equivalent K(1), two equivalent K(2), and two equivalent W(3) atoms. In the fifth O site, O(5) is bonded in a distorted linear geometry to two equivalent W(3) and two equivalent O(3) atoms. In the sixth O site, O(6) is bonded in a square co-planar geometry to two equivalent K(1) and two equivalent W(3) atoms. is represented by the CIF card [CIF]
