The material structure described by Ce5IrGe2 crystallizes in the orthorhombic Pnma space group. There are four inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 5-coordinate geometry to one Ir(1) and four equivalent Ge(1) atoms. In the second Ce site, Ce(2) is bonded to one Ir(1) and four equivalent Ge(1) atoms to form a mixture of distorted edge and corner-sharing CeGe4Ir trigonal bipyramids. In the third Ce site, Ce(3) is bonded to one Ir(1) and four equivalent Ge(1) atoms to form a mixture of distorted edge and corner-sharing CeGe4Ir square pyramids. In the fourth Ce site, Ce(4) is bonded in a 4-coordinate geometry to two equivalent Ir(1) and three equivalent Ge(1) atoms. Ir(1) is bonded in a 7-coordinate geometry to one Ce(1), one Ce(2), one Ce(3), and four equivalent Ce(4) atoms. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), two equivalent Ce(2), two equivalent Ce(3), and three equivalent Ce(4) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
