There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 6-coordinate geometry to two equivalent N(3) and four equivalent N(2) atoms. In the second Co site, Co(2) is bonded to two equivalent N(2) and four equivalent N(1) atoms to form distorted CoN6 pentagonal pyramids that share corners with two equivalent Ti(3)N6 pentagonal pyramids, corners with four equivalent Co(2)N6 pentagonal pyramids,  an edgeedge with one Ti(4)N6 pentagonal pyramid, edges with two equivalent Ti(2)N6 pentagonal pyramids, edges with two equivalent Ti(3)N6 pentagonal pyramids, and faces with two equivalent Ti(2)N6 pentagonal pyramids. There are three inequivalent N sites. In the first N site, N(1) is bonded to one Ti(1), one Ti(3), two equivalent Ti(2), and two equivalent Co(2) atoms to form a mixture of distorted face, corner, and edge-sharing NTi4Co2 pentagonal pyramids. In the second N site, N(2) is bonded to one Ti(1), one Ti(2), one Ti(3), one Ti(4), one Co(1), and one Co(2) atom to form a mixture of distorted face, corner, and edge-sharing NTi4Co2 pentagonal pyramids.
