Materials Data on RbSb3Se5 by Materials Project

RbSb3Se5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten Se2- atoms. There are a spread of Rb–Se bond distances ranging from 3.61–4.15 Å. There are three inequivalent Sb3+ sites. In the first Sb3+ site, Sb3+ is bonded in a distorted rectangular see-saw-like geometry to four Se2- atoms. There are a spread of Sb–Se bond distances ranging from 2.63–3.13 Å. In the second Sb3+ site, Sb3+ is bonded in a 3-coordinate geometry to three Se2- atoms. There are a spread of Sb–Se bond distances ranging from 2.57–2.69 Å. In the third Sb3+ site, Sb3+ is bonded in a distorted rectangular see-saw-like geometry to four Se2- atoms. There are a spread of Sb–Se bond distances ranging from 2.63–3.17 Å. There are five inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 5-coordinate geometry to two equivalent Rb1+ and three Sb3+ atoms. In the second Se2- site, Se2- is bonded in a 4-coordinate geometry to two equivalent Rb1+ and two Sb3+ atoms. In the third Se2- site, Se2- is bonded in a 2-coordinate geometry to two equivalent Rb1+ and two Sb3+ atoms. In the fourth Se2- site, Se2- is bonded in a 2-coordinate geometry to two equivalent Rb1+ and two Sb3+ atoms. In the fifth Se2- site, Se2- is bonded in a distorted L-shaped geometry to two equivalent Rb1+ and two Sb3+ atoms.
