MgIrN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Mg(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MgN4 tetrahedra that share corners with four equivalent Mg(1)N4 tetrahedra and corners with eight equivalent Ir(1)N4 tetrahedra. Ir(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted IrN4 tetrahedra that share corners with four equivalent Ir(1)N4 tetrahedra and corners with eight equivalent Mg(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mg(1) and two equivalent Ir(1) atoms to form corner-sharing NMg2Ir2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Ir(1) atoms to form corner-sharing NMg2Ir2 tetrahedra.
MgIrN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Mg(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MgN4 tetrahedra that share corners with four equivalent Mg(1)N4 tetrahedra and corners with eight equivalent Ir(1)N4 tetrahedra. Both Mg(1)-N(1) bond lengths are 2.11 Å. There is one shorter (2.07 Å) and one longer (2.13 Å) Mg(1)-N(2) bond length. Ir(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted IrN4 tetrahedra that share corners with four equivalent Ir(1)N4 tetrahedra and corners with eight equivalent Mg(1)N4 tetrahedra. Both Ir(1)-N(1) bond lengths are 1.96 Å. There is one shorter (1.93 Å) and one longer (2.06 Å) Ir(1)-N(2) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mg(1) and two equivalent Ir(1) atoms to form corner-sharing NMg2Ir2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Ir(1) atoms to form corner-sharing NMg2Ir2 tetrahedra.
