Materials Data on IrN2 by Materials Project
Abstract
IrN2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ir4+ is bonded to six N2- atoms to form IrN6 octahedra that share corners with eight equivalent IrN6 octahedra, corners with six NIr3N tetrahedra, and edges with two equivalent IrN6 octahedra. The corner-sharing octahedra tilt angles range from 65–69°. There are a spread of Ir–N bond distances ranging from 2.05–2.13 Å. There are two inequivalent N2- sites. In the first N2- site, N2- is bonded to three equivalent Ir4+ and one N2- atom to form distorted NIr3N tetrahedra that share corners with three equivalent IrN6 octahedra, corners with thirteen NIr3N tetrahedra, and an edgeedge with one NIr3N tetrahedra. The corner-sharing octahedra tilt angles range from 67–70°. The N–N bond length is 1.43 Å. In the second N2- site, N2- is bonded to three equivalent Ir4+ and one N2- atom to form NIr3N tetrahedra that share corners with three equivalent IrN6 octahedra, corners with thirteen NIr3N tetrahedra, and an edgeedge with one NIr3N tetrahedra. The corner-sharing octahedra tilt angles range from 64–66°.
