In the first Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Rb–Se bond distances ranging from 3.48–4.05 Å. In the second Rb1+ site, Rb1+ is bonded in a 7-coordinate geometry to seven Se2- atoms. There are a spread of Rb–Se bond distances ranging from 3.57–4.14 Å. There are four inequivalent Sn+3.50+ sites. In the first Sn+3.50+ site, Sn+3.50+ is bonded to four Se2- atoms to form a mixture of corner and edge-sharing SnSe4 tetrahedra. There are a spread of Sn–Se bond distances ranging from 2.50–2.61 Å. In the second Sn+3.50+ site, Sn+3.50+ is bonded to four Se2- atoms to form corner-sharing SnSe4 tetrahedra. There are a spread of Sn–Se bond distances ranging from 2.54–2.61 Å. In the third Sn+3.50+ site, Sn+3.50+ is bonded to four Se2- atoms to form a mixture of corner and edge-sharing SnSe4 tetrahedra.
