The material described by Sr5(CoN2)2 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted square co-planar geometry to four equivalent N(1) atoms. In the second Sr site, Sr(2) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. Co(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded in a 6-coordinate geometry to one Sr(1), four equivalent Sr(2), and one Co(1) atom. is represented by the CIF card [CIF]
