The compound described by RbSrSiHO4 crystallizes in the monoclinic P2_1 space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent H(1), two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Sr(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form SrO6 octahedra that share corners with six equivalent Si(1)O4 tetrahedra and edges with two equivalent Sr(1)O6 octahedra. Si(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SiO4 tetrahedra that share corners with six equivalent Sr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-53°. H(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1), two equivalent Sr(1), and one Si(1) atom. In the second O site, O(2) is bonded in a 1-coordinate geometry to two equivalent Rb(1), two equivalent Sr(1), and one Si(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Rb(1), one Sr(1), one Si(1), and one H(1) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent Rb(1), one Sr(1), one Si(1), and one H(1) atom. is represented by the CIF file [CIF]
