The compound described by Ce3Ir is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a distorted L-shaped geometry to three equivalent Ir(1) atoms. In the second Ce site, Ce(2) is bonded in a distorted bent 150 degrees geometry to three equivalent Ir(1) atoms. Ir(1) is bonded in a 9-coordinate geometry to three equivalent Ce(2) and six equivalent Ce(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
