The structure described by SrSnN2 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 4-coordinate geometry to two equivalent N(1) and three equivalent N(2) atoms. Sn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of edge and corner-sharing SnN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Sr(1) and two equivalent Sn(1) atoms to form a mixture of edge and corner-sharing NSr2Sn2 tetrahedra. In the second N site, N(2) is bonded in a 5-coordinate geometry to three equivalent Sr(1) and two equivalent Sn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
