The structure described by KEu(WO4)2 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 10-coordinate geometry to two equivalent O(1), two equivalent O(3), two equivalent O(4), and four equivalent O(2) atoms. Eu(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. W(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form a mixture of edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 40°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one Eu(1), and one W(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent W(1) atoms. In the third O site, O(3) is bonded to one K(1), one Eu(1), and two equivalent W(1) atoms to form a mixture of distorted edge and corner-sharing OKEuW2 tetrahedra. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to one K(1), one Eu(1), and one W(1) atom. is represented by the CIF card [CIF]
