The structure described by Rb2Ni(SO7)2 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 8-coordinate geometry to one O(1), one O(3), one O(4), one O(5), two equivalent O(2), and two equivalent O(7) atoms. Ni(1) is bonded in a distorted octahedral geometry to two equivalent O(3), two equivalent O(5), and two equivalent O(6) atoms. S(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(4), and one O(7) atom. There are seven inequivalent O sites. In the first O site, O(7) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one S(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to one Rb(1) and one S(1) atom. In the third O site, O(2) is bonded in a single-bond geometry to two equivalent Rb(1) and one S(1) atom. In the fourth O site, O(3) is bonded in a single-bond geometry to one Rb(1) and one Ni(1) atom. In the fifth O site, O(4) is bonded in a distorted single-bond geometry to one Rb(1) and one S(1) atom. In the sixth O site, O(5) is bonded in a distorted single-bond geometry to one Rb(1) and one Ni(1) atom. In the seventh O site, O(6) is bonded in a single-bond geometry to one Ni(1) atom. is represented by the CIF file [CIF]
