The structure described by Co2TiSi crystallizes in the monoclinic Cm space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 12-coordinate geometry to one Ti(2), one Co(3), two equivalent Co(2), three equivalent Co(1), two equivalent Si(1), and three equivalent Si(2) atoms. In the second Ti site, Ti(2) is bonded in a 14-coordinate geometry to one Ti(1), two equivalent Co(1), two equivalent Co(3), four equivalent Co(2), two equivalent Si(2), and three equivalent Si(1) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 8-coordinate geometry to two equivalent Ti(2), three equivalent Ti(1), two equivalent Co(3), one Si(1), and two equivalent Si(2) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to one Ti(1), two equivalent Ti(2), two equivalent Co(2), two equivalent Co(3), one Si(1), and one Si(2) atom. In the third Co site, Co(3) is bonded in a 11-coordinate geometry to one Ti(1), two equivalent Ti(2), two equivalent Co(1), four equivalent Co(2), one Si(1), and one Si(2) atom. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 10-coordinate geometry to two equivalent Ti(1), three equivalent Ti(2), one Co(1), one Co(3), two equivalent Co(2), and one Si(2) atom. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to two equivalent Ti(2), three equivalent Ti(1), one Co(3), two equivalent Co(1), two equivalent Co(2), and one Si(1) atom. is represented by the CIF file [CIF]
