The material described by Sr5(CoN3)2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 6-coordinate geometry to two equivalent N(1), two equivalent N(2), and two equivalent N(3) atoms. In the second Sr site, Sr(2) is bonded to one N(3), two equivalent N(1), and two equivalent N(2) atoms to form distorted SrN5 trigonal bipyramids that share corners with two equivalent Co(1)N4 tetrahedra, corners with two equivalent Sr(2)N5 trigonal bipyramids, edges with two equivalent Co(1)N4 tetrahedra, and  an edgeedge with one Sr(2)N5 trigonal bipyramid. In the third Sr site, Sr(3) is bonded in a 6-coordinate geometry to two equivalent N(1), two equivalent N(2), and two equivalent N(3) atoms. Co(1) is bonded to one N(1), one N(2), and two equivalent N(3) atoms to form CoN4 tetrahedra that share corners with two equivalent Sr(2)N5 trigonal bipyramids,  an edgeedge with one Co(1)N4 tetrahedra, and edges with two equivalent Sr(2)N5 trigonal bipyramids. There are three inequivalent N sites. In the first N site, N(2) is bonded to one Sr(3), two equivalent Sr(1), two equivalent Sr(2), and one Co(1) atom to form a mixture of distorted corner and edge-sharing NSr5Co octahedra. The corner-sharing octahedral tilt angles range from 18-76°. In the second N site, N(3) is bonded in a 6-coordinate geometry to one Sr(2), one Sr(3), two equivalent Sr(1), and two equivalent Co(1) atoms. In the third N site, N(1) is bonded to one Sr(3), two equivalent Sr(1), two equivalent Sr(2), and one Co(1) atom to form a mixture of distorted face, corner, and edge-sharing NSr5Co octahedra. The corner-sharing octahedral tilt angles range from 18-76°. is represented by the CIF file [CIF]
