The crystal structure described by Sr3(CoN2)2 crystallizes in the orthorhombic Pnna space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 4-coordinate geometry to three equivalent N(1) and three equivalent N(2) atoms. In the second Sr site, Sr(2) is bonded to two equivalent N(2) and four equivalent N(1) atoms to form distorted SrN6 octahedra that share corners with six equivalent Co(2)N4 tetrahedra, edges with two equivalent Sr(2)N6 octahedra, and edges with three equivalent Co(1)N4 tetrahedra. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CoN4 tetrahedra that share edges with three equivalent Sr(2)N6 octahedra and edges with two equivalent Co(2)N4 tetrahedra. In the second Co site, Co(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted CoN4 tetrahedra that share corners with six equivalent Sr(2)N6 octahedra and edges with two equivalent Co(1)N4 tetrahedra. The corner-sharing octahedral tilt angles range from 32-78°. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 7-coordinate geometry to two equivalent Sr(2), three equivalent Sr(1), one Co(1), and one Co(2) atom. In the second N site, N(2) is bonded to one Sr(2), three equivalent Sr(1), one Co(1), and one Co(2) atom to form a mixture of distorted edge, corner, and face-sharing NSr4Co2 octahedra. The corner-sharing octahedral tilt angles range from 54-62°. is represented by the Crystallographic Information File (CIF) [CIF]
