Cs2CrO4 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 9-coordinate geometry to two equivalent O(3), three equivalent O(2), and four equivalent O(1) atoms. In the second Cs site, Cs(2) is bonded in a 11-coordinate geometry to two equivalent O(2), three equivalent O(3), and six equivalent O(1) atoms. Cr(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Cs(1), three equivalent Cs(2), and one Cr(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Cs(2), three equivalent Cs(1), and one Cr(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Cs(1), three equivalent Cs(2), and one Cr(1) atom.

In the first Cs site, Cs(1) is bonded in a 9-coordinate geometry to two equivalent O(3), three equivalent O(2), and four equivalent O(1) atoms. There is one shorter (3.00 Å) and one longer (3.18 Å) Cs(1)-O(3) bond length. There is one shorter (3.21 Å) and two longer (3.36 Å) Cs(1)-O(2) bond lengths. All Cs(1)-O(1) bond lengths are 3.09 Å. In the second Cs site, Cs(2) is bonded in a 11-coordinate geometry to two equivalent O(2), three equivalent O(3), and six equivalent O(1) atoms. There is one shorter (3.16 Å) and one longer (3.74 Å) Cs(2)-O(2) bond length. There are two shorter (3.18 Å) and one longer (3.60 Å) Cs(2)-O(3) bond length. There are a spread of Cs(2)-O(1) bond distances ranging from 3.20-3.45 Å. Cr(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms.
