The structure described by Ti2Co crystallizes in the cubic Fd-3m space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 6-coordinate geometry to six equivalent Co(1) atoms. In the second Ti site, Ti(2) is bonded in a 2-coordinate geometry to two equivalent Co(1) atoms. Co(1) is bonded in a 6-coordinate geometry to three equivalent Ti(1) and three equivalent Ti(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
