(CoFe)Ti2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two (CoFe)Ti2 ribbons oriented in the (1, 0, 0) direction. Ti is bonded in a linear geometry to one Fe and one Co atom. The Ti–Fe bond length is 1.94 Å. The Ti–Co bond length is 2.02 Å. Fe is bonded in a linear geometry to two equivalent Ti atoms. Co is bonded in a linear geometry to two equivalent Ti atoms.
(CoFe)Ti2 is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ti is bonded in a body-centered cubic geometry to four equivalent Fe and four equivalent Co atoms. All Ti–Fe bond lengths are 2.57 Å. All Ti–Co bond lengths are 2.57 Å. Fe is bonded in a body-centered cubic geometry to eight equivalent Ti atoms. Co is bonded in a body-centered cubic geometry to eight equivalent Ti atoms.
