The structure described by Cs5YO4 crystallizes in the monoclinic P2_1/c space group. There are five inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a distorted rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. In the second Cs site, Cs(2) is bonded in a 4-coordinate geometry to one O(1), one O(3), and two equivalent O(2) atoms. In the third Cs site, Cs(3) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(4) atoms. In the fourth Cs site, Cs(4) is bonded in a 4-coordinate geometry to one O(2), one O(3), and two equivalent O(4) atoms. In the fifth Cs site, Cs(5) is bonded to one O(2), one O(3), and two equivalent O(4) atoms to form distorted CsO4 tetrahedra that share corners with two equivalent Cs(5)O4 tetrahedra, corners with two equivalent Y(1)O4 tetrahedra, and  an edgeedge with one Y(1)O4 tetrahedra. Y(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form YO4 tetrahedra that share corners with two equivalent Cs(5)O4 tetrahedra and  an edgeedge with one Cs(5)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Cs(2), two equivalent Cs(1), two equivalent Cs(3), and one Y(1) atom to form a mixture of distorted edge and corner-sharing OCs5Y octahedra. The corner-sharing octahedral tilt angles range from 47-66°. In the second O site, O(2) is bonded to one Cs(1), one Cs(4), one Cs(5), two equivalent Cs(2), and one Y(1) atom to form a mixture of distorted edge and corner-sharing OCs5Y octahedra. The corner-sharing octahedral tilt angles range from 47-66°. In the third O site, O(3) is bonded in a 6-coordinate geometry to one Cs(1), one Cs(2), one Cs(3), one Cs(4), one Cs(5), and one Y(1) atom. In the fourth O site, O(4) is bonded in a 7-coordinate geometry to two equivalent Cs(3), two equivalent Cs(4), two equivalent Cs(5), and one Y(1) atom. is represented by the CIF card [CIF]
