The compound described by Sr3Co3N5 crystallizes in the triclinic P-1 space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to one N(3), one N(4), one N(5), and two equivalent N(2) atoms. In the second Sr site, Sr(2) is bonded in a 7-coordinate geometry to one N(2), one N(3), one N(4), two equivalent N(1), and two equivalent N(5) atoms. In the third Sr site, Sr(3) is bonded in a 5-coordinate geometry to one N(1), one N(2), one N(4), and two equivalent N(3) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded to one N(1), one N(5), and two equivalent N(3) atoms to form a mixture of corner and edge-sharing CoN4 tetrahedra. In the second Co site, Co(2) is bonded to one N(1), one N(2), and two equivalent N(4) atoms to form a mixture of corner and edge-sharing CoN4 tetrahedra. In the third Co site, Co(3) is bonded to one N(1), one N(2), one N(4), and one N(5) atom to form a mixture of corner and edge-sharing CoN4 tetrahedra. There are five inequivalent N sites. In the first N site, N(1) is bonded in a 6-coordinate geometry to one Sr(3), two equivalent Sr(2), one Co(1), one Co(2), and one Co(3) atom. In the second N site, N(2) is bonded in a 6-coordinate geometry to one Sr(2), one Sr(3), two equivalent Sr(1), one Co(2), and one Co(3) atom. In the third N site, N(3) is bonded to one Sr(1), one Sr(2), two equivalent Sr(3), and two equivalent Co(1) atoms to form distorted edge-sharing NSr4Co2 octahedra. In the fourth N site, N(4) is bonded in a 6-coordinate geometry to one Sr(1), one Sr(2), one Sr(3), one Co(3), and two equivalent Co(2) atoms. In the fifth N site, N(5) is bonded in a 2-coordinate geometry to one Sr(1), two equivalent Sr(2), one Co(1), and one Co(3) atom. is represented by the CIF card [CIF]
