The material described by TiCoGe2 crystallizes in the orthorhombic Pbam space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 8-coordinate geometry to one Ge(4), one Ge(5), two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. In the second Ti site, Ti(2) is bonded in a 7-coordinate geometry to two equivalent Ge(1), two equivalent Ge(2), and three equivalent Ge(4) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 6-coordinate geometry to one Ge(2), one Ge(3), one Ge(4), one Ge(5), and two equivalent Ge(1) atoms. In the second Co site, Co(2) is bonded to two equivalent Ge(1), two equivalent Ge(4), and two equivalent Ge(5) atoms to form distorted edge-sharing CoGe6 cuboctahedra. There are five inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Ti(2), four equivalent Ti(1), two equivalent Co(1), and one Ge(2) atom. In the second Ge site, Ge(3) is bonded in a 7-coordinate geometry to four equivalent Ti(1), two equivalent Co(1), and one Ge(3) atom. In the third Ge site, Ge(4) is bonded in a 9-coordinate geometry to two equivalent Ti(1), three equivalent Ti(2), two equivalent Co(1), and two equivalent Co(2) atoms. In the fourth Ge site, Ge(5) is bonded in a 6-coordinate geometry to two equivalent Ti(1), two equivalent Co(1), and two equivalent Co(2) atoms. In the fifth Ge site, Ge(1) is bonded in a 7-coordinate geometry to one Ti(2), two equivalent Ti(1), one Co(2), two equivalent Co(1), and one Ge(1) atom. is represented by the CIF file [CIF]
