Materials Data on CsGaBr4 by Materials Project
CsGaBr4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cs1+ is bonded in a 10-coordinate geometry to ten Br1- atoms. There are a spread of Cs–Br bond distances ranging from 3.82–4.24 Å. Ga3+ is bonded in a tetrahedral geometry to four Br1- atoms. There are a spread of Ga–Br bond distances ranging from 2.34–2.37 Å. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a distorted single-bond geometry to one Cs1+ and one Ga3+ atom. In the second Br1- site, Br1- is bonded in a distorted single-bond geometry to three equivalent Cs1+ and one Ga3+ atom. In the third Br1- site, Br1- is bonded in a distorted single-bond geometry to three equivalent Cs1+ and one Ga3+ atom.
