Materials Data on IrF4 by Materials Project
IrF4 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. Ir4+ is bonded to six F1- atoms to form corner-sharing IrF6 octahedra. The corner-sharing octahedral tilt angles are 48°. There are a spread of Ir–F bond distances ranging from 1.89–2.05 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Ir4+ atom. In the second F1- site, F1- is bonded in a distorted bent 120 degrees geometry to two equivalent Ir4+ atoms.
