The structure described by IrF4 crystallizes in the orthorhombic Fdd2 space group. Ir(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form corner-sharing IrF6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are two inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one Ir(1) atom. In the second F site, F(2) is bonded in a bent 120 degrees geometry to two equivalent Ir(1) atoms. is represented by the CIF file [CIF]
