Cs2VHO4 crystallizes in the orthorhombic Cmc2_1 space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 7-coordinate geometry to one H(1), two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. In the second Cs site, Cs(2) is bonded in a 3-coordinate geometry to one O(3) and two equivalent O(1) atoms. V(1) is bonded in a tetrahedral geometry to one O(1), one O(3), and two equivalent O(2) atoms. H(1) is bonded in a linear geometry to one Cs(1) and two equivalent O(2) 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), two equivalent Cs(2), and one V(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Cs(1), one V(1), and one H(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Cs(2), two equivalent Cs(1), and one V(1) atom.
