Materials Data on Cs3GaO3 by Materials Project
Cs3GaO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Cs–O bond distances ranging from 2.84–3.42 Å. In the second Cs1+ site, Cs1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Cs–O bond distances ranging from 3.01–3.14 Å. In the third Cs1+ site, Cs1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Cs–O bond distances ranging from 2.96–3.25 Å. Ga3+ is bonded to four O2- atoms to form edge-sharing GaO4 tetrahedra. There are a spread of Ga–O bond distances ranging from 1.87–1.98 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to six Cs1+ and one Ga3+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to three Cs1+ and two equivalent Ga3+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to four Cs1+ and one Ga3+ atom.
