The crystal structure described by SrIrN2 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 5-coordinate geometry to two equivalent N(2) and four equivalent N(1) atoms. Ir(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of distorted edge and corner-sharing IrN4 trigonal pyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 6-coordinate geometry to four equivalent Sr(1) and two equivalent Ir(1) atoms. In the second N site, N(2) is bonded in a 4-coordinate geometry to two equivalent Sr(1) and two equivalent Ir(1) atoms. is represented by the CIF file [CIF]
