The structure described by Cs4Sb2O5 crystallizes in the monoclinic Cm space group. There are four inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second Cs site, Cs(2) is bonded in a 8-coordinate geometry to one Sb(1), one Sb(2), two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. In the third Cs site, Cs(3) is bonded in a 7-coordinate geometry to one O(3), two equivalent O(1), and four equivalent O(2) atoms. In the fourth Cs site, Cs(4) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted trigonal non-coplanar geometry to one Cs(2), one O(3), and two equivalent O(1) atoms. In the second Sb site, Sb(2) is bonded in a 3-coordinate geometry to one Cs(2), one O(3), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to one Cs(1), one Cs(2), one Cs(3), two equivalent Cs(4), and one Sb(1) atom. In the second O site, O(2) is bonded in a 6-coordinate geometry to one Cs(1), one Cs(2), one Cs(4), two equivalent Cs(3), and one Sb(2) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Cs(3), two equivalent Cs(2), one Sb(1), and one Sb(2) atom. is represented by the CIF card [CIF]
