Materials Data on KRb3CdCl6 by Materials Project
Rb3KCdCl6 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight equivalent Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.38–3.53 Å. K1+ is bonded in a 6-coordinate geometry to six equivalent Cl1- atoms. All K–Cl bond lengths are 3.14 Å. Cd2+ is bonded in an octahedral geometry to six equivalent Cl1- atoms. All Cd–Cl bond lengths are 2.69 Å. Cl1- is bonded to four equivalent Rb1+, one K1+, and one Cd2+ atom to form a mixture of distorted corner, edge, and face-sharing ClKRb4Cd octahedra. The corner-sharing octahedra tilt angles range from 0–64°.
