RbZnH2Se2O6Br crystallizes in the monoclinic P2/c space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent Br(1) atoms. Zn(1) is bonded in a distorted trigonal bipyramidal geometry to two equivalent O(2), two equivalent O(3), and one Br(1) atom. H(1) is bonded in a distorted linear geometry to one O(1) and one O(3) atom. Se(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Rb(1), one H(1), and one Se(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Rb(1), one Zn(1), and one Se(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Rb(1), one Zn(1), one H(1), and one Se(1) atom. Br(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one Zn(1) atom.
