The material structure described by SrCrN2 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 8-coordinate geometry to four equivalent N(1) and four equivalent N(2) atoms. Cr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of corner and edge-sharing CrN4 tetrahedra. 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 Cr(1) atoms. In the second N site, N(2) is bonded in a 2-coordinate geometry to four equivalent Sr(1) and two equivalent Cr(1) atoms. is represented by the CIF card [CIF]
