The structure described by Sr2BN2F crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 6-coordinate geometry to one N(2), two equivalent N(1), and three equivalent F(1) atoms. In the second Sr site, Sr(2) is bonded to two equivalent N(2), three equivalent N(1), and one F(1) atom to form distorted edge-sharing SrN5F octahedra. B(1) is bonded in a linear geometry to one N(1) and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted single-bond geometry to two equivalent Sr(1), three equivalent Sr(2), and one B(1) atom. In the second N site, N(2) is bonded to one Sr(1), two equivalent Sr(2), and one B(1) atom to form distorted NSr3B trigonal pyramids that share corners with five equivalent F(1)Sr4 tetrahedra and corners with two equivalent N(2)Sr3B trigonal pyramids. F(1) is bonded to one Sr(2) and three equivalent Sr(1) atoms to form FSr4 tetrahedra that share corners with two equivalent F(1)Sr4 tetrahedra, corners with five equivalent N(2)Sr3B trigonal pyramids, and edges with two equivalent F(1)Sr4 tetrahedra. is represented by the CIF file [CIF]
