Materials Data on RbCdBr3 by Materials Project
RbCdBr3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb1+ is bonded in a 9-coordinate geometry to eight Br1- atoms. There are a spread of Rb–Br bond distances ranging from 3.55–3.75 Å. Cd2+ is bonded to six Br1- atoms to form edge-sharing CdBr6 octahedra. There are a spread of Cd–Br bond distances ranging from 2.69–2.92 Å. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 4-coordinate geometry to one Rb1+ and three equivalent Cd2+ atoms. In the second Br1- site, Br1- is bonded in a 5-coordinate geometry to three equivalent Rb1+ and two equivalent Cd2+ atoms. In the third Br1- site, Br1- is bonded in a 5-coordinate geometry to four equivalent Rb1+ and one Cd2+ atom.
