In the second In3+ site, In3+ is bonded to four Se2- atoms to form corner-sharing InSe4 tetrahedra. There are one shorter (2.63 Å) and three longer (2.64 Å) In–Se bond lengths. There are five inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 2-coordinate geometry to four Rb1+ and two equivalent In3+ atoms. In the second Se2- site, Se2- is bonded in a 2-coordinate geometry to four Rb1+ and two equivalent In3+ atoms. In the third Se2- site, Se2- is bonded in a 2-coordinate geometry to four Rb1+ and two In3+ atoms. In the fourth Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to two Rb1+ and two In3+ atoms. In the fifth Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to two Rb1+ and two In3+ atoms.
