The structure described by Ho3Ir is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms. In the second Ho site, Ho(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ir(1) atoms. Ir(1) is bonded in a 8-coordinate geometry to two equivalent Ho(2) and six equivalent Ho(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
