The structure described by CsAu5Ga9 crystallizes in the hexagonal P6_3/mmc space group. Cs(1) is bonded in a 24-coordinate geometry to six equivalent Au(2), six equivalent Ga(2), and twelve equivalent Ga(1) atoms. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted q6 geometry to three equivalent Ga(2) and six equivalent Ga(1) atoms. In the second Au site, Au(2) is bonded in a 6-coordinate geometry to two equivalent Cs(1), two equivalent Ga(2), and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to two equivalent Cs(1), two equivalent Au(1), and two equivalent Au(2) atoms. In the second Ga site, Ga(2) is bonded to two equivalent Cs(1), two equivalent Au(1), and two equivalent Au(2) atoms to form a mixture of distorted corner, face, and edge-sharing GaCs2Au4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
