In the first Cs1+ site, Cs1+ is bonded in a 4-coordinate geometry to six Sb3- atoms. There are a spread of Cs–Sb bond distances ranging from 4.08–4.44 Å. In the second Cs1+ site, Cs1+ is bonded in a 3-coordinate geometry to four Sb3- atoms. There are a spread of Cs–Sb bond distances ranging from 3.86–4.49 Å. In the third Cs1+ site, Cs1+ is bonded in a 4-coordinate geometry to four Sb3- atoms. There are a spread of Cs–Sb bond distances ranging from 4.07–4.12 Å. In the fourth Cs1+ site, Cs1+ is bonded to four Sb3- atoms to form a mixture of distorted corner and edge-sharing CsSb4 tetrahedra. There are a spread of Cs–Sb bond distances ranging from 3.88–4.14 Å. In the fifth Cs1+ site, Cs1+ is bonded in a 5-coordinate geometry to five Sb3- atoms. There are a spread of Cs–Sb bond distances ranging from 4.13–4.18 Å. In the sixth Cs1+ site, Cs1+ is bonded to four Sb3- atoms to form a mixture of distorted corner and edge-sharing CsSb4 trigonal pyramids. There are one shorter (3.93 Å) and three longer (3.95 Å) Cs–Sb bond lengths. Ga3+ is bonded in a trigonal planar geometry to three Sb3- atoms. There are a spread of Ga–Sb bond distances ranging from 2.66–2.73 Å. There are three inequivalent Sb3- sites. In the first Sb3- site, Sb3- is bonded in a 1-coordinate geometry to ten Cs1+ and one Ga3+ atom. In the second Sb3- site, Sb3- is bonded in a 1-coordinate geometry to seven Cs1+ and one Ga3+ atom. In the third Sb3- site, Sb3- is bonded in a 1-coordinate geometry to ten Cs1+ and one Ga3+ atom.
