The material structure described by Rb6Si10O23 crystallizes in the hexagonal P-62m space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 10-coordinate geometry to two equivalent O(3), four equivalent O(2), and four equivalent O(4) atoms. In the second Rb site, Rb(2) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded to one O(2), one O(3), and two equivalent O(4) atoms to form corner-sharing SiO4 tetrahedra. In the second Si site, Si(2) is bonded to one O(1) and three equivalent O(4) atoms to form corner-sharing SiO4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Si(2) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Rb(1), two equivalent Rb(2), and one Si(1) atom. In the third O site, O(3) is bonded in a linear geometry to two equivalent Rb(1) and two equivalent Si(1) atoms. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Rb(1), one Si(1), and one Si(2) atom. is represented by the CIF card [CIF]
