The structure described by SrN crystallizes in the monoclinic C2/m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to three equivalent N(2) and four equivalent N(1) atoms to form a mixture of distorted face and edge-sharing SrN7 pentagonal bipyramids. In the second Sr site, Sr(2) is bonded in a rectangular see-saw-like geometry to one N(1) and three equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 6-coordinate geometry to one Sr(2), four equivalent Sr(1), and one N(1) atom. In the second N site, N(2) is bonded to three equivalent Sr(1) and three equivalent Sr(2) atoms to form edge-sharing NSr6 octahedra. is represented by the Crystallographic Information File (CIF) [CIF]
