The material structure described by SrMnN2 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 4-coordinate geometry to one N(2) and four equivalent N(1) atoms. Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of corner and edge-sharing MnN4 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 Mn(1) atoms. In the second N site, N(2) is bonded in a 3-coordinate geometry to one Sr(1) and two equivalent Mn(1) atoms. is represented by the CIF file [CIF]
