The structure described by RbCuSb2H2Se4O crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent H(1), one Se(2), two equivalent Se(1), two equivalent Se(3), and three equivalent O(1) atoms. Cu(1) is bonded to one Se(2), one Se(4), and two equivalent Se(1) atoms to form CuSe4 tetrahedra that share corners with two equivalent Sb(1)Se5 square pyramids and corners with two equivalent Cu(1)Se4 tetrahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to two equivalent Se(2) and three equivalent Se(3) atoms to form SbSe5 square pyramids that share corners with two equivalent Cu(1)Se4 tetrahedra and edges with four equivalent Sb(1)Se5 square pyramids. In the second Sb site, Sb(2) is bonded in a 3-coordinate geometry to one Se(1), two equivalent Se(2), and two equivalent Se(4) atoms. H(1) is bonded in a single-bond geometry to one Rb(1) and one O(1) atom. There are four inequivalent Se sites. In the first Se site, Se(1) is bonded in a 5-coordinate geometry to two equivalent Rb(1), two equivalent Cu(1), and one Sb(2) atom. In the second Se site, Se(2) is bonded in a 6-coordinate geometry to one Rb(1), one Cu(1), two equivalent Sb(1), and two equivalent Sb(2) atoms. In the third Se site, Se(3) is bonded to two equivalent Rb(1) and three equivalent Sb(1) atoms to form distorted edge-sharing SeRb2Sb3 square pyramids.
