The compound described by Ce5PdGe2 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to two equivalent Pd(1) and four equivalent Ge(1) atoms to form corner-sharing CeGe4Pd2 octahedra. The corner-sharing octahedral tilt angles range from 0-55°. In the second Ce site, Ce(2) is bonded in a 5-coordinate geometry to two equivalent Pd(1) and three equivalent Ge(1) atoms. Pd(1) is bonded in a distorted q6 geometry to two equivalent Ce(1) and eight equivalent Ce(2) atoms. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), six equivalent Ce(2), and one Ge(1) atom. is represented by the CIF file [CIF]
