Materials Data on Rb4CdCl6 by Materials Project

Abstract

Rb4CdCl6 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.22–3.67 Å. In the second Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.18–3.91 Å. In the third Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six Cl1- atoms. There are two shorter (3.12 Å) and four longer (3.47 Å) Rb–Cl bond lengths. Cd2+ is bonded in a square co-planar geometry to four Cl1- atoms. There are two shorter (2.50 Å) and two longer (2.63 Å) Cd–Cl bond lengths. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four Rb1+ and one Cd2+ atom. In the second Cl1- site, Cl1- is bonded to four Rb1+ atoms to form a mixture of distorted edge and corner-sharing ClRb4 trigonal pyramids. In the third Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four Rb1+ and one Cd2+ atom.
