The material described by SnN is beta beryllia-like structured and crystallizes in the monoclinic Cm space group. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to one N(1) and three equivalent N(2) atoms to form corner-sharing SnN4 tetrahedra. In the second Sn site, Sn(2) is bonded to one N(2) and three equivalent N(1) atoms to form corner-sharing SnN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Sn(1) and three equivalent Sn(2) atoms to form corner-sharing NSn4 tetrahedra. In the second N site, N(2) is bonded to one Sn(2) and three equivalent Sn(1) atoms to form corner-sharing NSn4 tetrahedra. is represented by the CIF file [CIF]
