The compound described by Ce8Pd24Ga crystallizes in the cubic Pm-3m space group. Ce(1) is bonded to three equivalent Pd(1), three equivalent Pd(2), and six equivalent Pd(3) atoms to form CePd12 cuboctahedra that share corners with twelve equivalent Ce(1)Pd12 cuboctahedra, faces with six equivalent Ce(1)Pd12 cuboctahedra, and  a faceface with one Ga(1)Pd6 octahedra. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent Ce(1) atoms. In the second Pd site, Pd(2) is bonded in a 5-coordinate geometry to four equivalent Ce(1) and one Ga(1) atom. In the third Pd site, Pd(3) is bonded in a distorted square co-planar geometry to four equivalent Ce(1) atoms. Ga(1) is bonded to six equivalent Pd(2) atoms to form GaPd6 octahedra that share faces with eight equivalent Ce(1)Pd12 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
