SrIrN2 crystallizes in the tetragonal P4/nmm space group. Sr(1) is bonded to five equivalent N(2) atoms to form a mixture of edge and corner-sharing SrN5 square pyramids. Ir(1) is bonded in a 5-coordinate geometry to one N(2) and four equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to four equivalent Ir(1) atoms. In the second N site, N(2) is bonded to five equivalent Sr(1) and one Ir(1) atom to form a mixture of edge and corner-sharing NSr5Ir octahedra. The corner-sharing octahedral tilt angles are 1°.
SrIrN2 crystallizes in the tetragonal P4/nmm space group. Sr(1) is bonded to five equivalent N(2) atoms to form a mixture of edge and corner-sharing SrN5 square pyramids. There is one shorter (2.52 Å) and four longer (2.78 Å) Sr(1)-N(2) bond lengths. Ir(1) is bonded in a 5-coordinate geometry to one N(2) and four equivalent N(1) atoms. The Ir(1)-N(2) bond length is 1.97 Å. All Ir(1)-N(1) bond lengths are 2.09 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to four equivalent Ir(1) atoms. In the second N site, N(2) is bonded to five equivalent Sr(1) and one Ir(1) atom to form a mixture of edge and corner-sharing NSr5Ir octahedra. The corner-sharing octahedral tilt angles are 1°.
