The structure described by IrC4 is lead oxide-like structured and crystallizes in the orthorhombic Ccce space group. Ir(1) is bonded in a 4-coordinate geometry to four equivalent C(1) atoms. C(1) is bonded to one Ir(1) and three equivalent C(1) atoms to form distorted corner-sharing CIrC3 tetrahedra. is represented by the CIF file [CIF]
