Materials Data on Rb2BaCl4 by Materials Project
Rb2BaCl4 crystallizes in the tetragonal I-42d 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 3.24–3.53 Å. Ba2+ is bonded to eight equivalent Cl1- atoms to form distorted edge-sharing BaCl8 hexagonal bipyramids. There are four shorter (3.16 Å) and four longer (3.41 Å) Ba–Cl bond lengths. Cl1- is bonded in a 6-coordinate geometry to four equivalent Rb1+ and two equivalent Ba2+ atoms.
