IrZn4N4 crystallizes in the triclinic P-1 space group. Ir(1) is bonded in a 4-coordinate geometry to one N(1), one N(2), one N(3), and one N(4) atom. There are four inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one N(4) atom. In the second Zn site, Zn(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent N(2) and two equivalent N(3) atoms. In the third Zn site, Zn(3) is bonded in a distorted rectangular see-saw-like geometry to one N(1), one N(3), and two equivalent N(4) atoms.
