The material described by Sr3(MnN2)2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 6-coordinate geometry to two equivalent N(2) and four equivalent N(1) atoms. In the second Sr site, Sr(2) is bonded to two equivalent N(1) and four equivalent N(2) atoms to form distorted SrN6 octahedra that share corners with four equivalent Mn(1)N4 tetrahedra, edges with two equivalent Sr(2)N6 octahedra, and edges with four equivalent Mn(1)N4 tetrahedra. Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MnN4 tetrahedra that share corners with two equivalent Sr(2)N6 octahedra, corners with two equivalent Mn(1)N4 tetrahedra, edges with two equivalent Sr(2)N6 octahedra, and  an edgeedge with one Mn(1)N4 tetrahedra. The corner-sharing octahedral tilt angles range from 46-49°. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 7-coordinate geometry to one Sr(2), four equivalent Sr(1), and two equivalent Mn(1) atoms. In the second N site, N(2) is bonded in a 2-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
