The crystal structure described by K2W3Te2O5 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), and two equivalent O(5) atoms. In the second K site, K(2) is bonded in a 5-coordinate geometry to one O(2), one O(3), one O(5), and two equivalent O(4) atoms. There are three inequivalent W sites. In the first W site, W(1) is bonded in a distorted linear geometry to one O(3) and one O(5) atom. In the second W site, W(2) is bonded in a single-bond geometry to one O(1) atom. In the third W site, W(3) is bonded in a distorted single-bond geometry to one O(1) atom. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted see-saw-like geometry to one O(1), one O(2), and two equivalent O(4) atoms. In the second Te site, Te(2) is bonded in a 3-coordinate geometry to one O(2), one O(3), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(2) is bonded in a 1-coordinate geometry to one K(1), one K(2), one Te(1), and one Te(2) atom. In the second O site, O(3) is bonded in a trigonal pyramidal geometry to one K(1), one K(2), one W(1), and one Te(2) atom. In the third O site, O(4) is bonded in a 4-coordinate geometry to two equivalent K(2) and two equivalent Te(1) atoms. In the fourth O site, O(5) is bonded in a 5-coordinate geometry to one K(2), two equivalent K(1), one W(1), and one Te(2) atom. In the fifth O site, O(1) is bonded in a rectangular see-saw-like geometry to one K(1), one W(2), one W(3), and one Te(1) atom. is represented by the CIF card [CIF]
