The compound described by Ge2MnTi 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 to two equivalent Ge(1), two equivalent Ge(2), and three equivalent Ge(4) atoms to form a mixture of distorted edge and corner-sharing TiGe7 pentagonal bipyramids. There are two inequivalent Mn sites. In the first Mn site, Mn(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 Mn site, Mn(2) is bonded in a 6-coordinate geometry to two equivalent Ge(1), two equivalent Ge(4), and two equivalent Ge(5) atoms. 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 Mn(1), and one Ge(2) atom. In the second Ge site, Ge(3) is bonded in a 2-coordinate geometry to four equivalent Ti(1) and two equivalent Mn(1) atoms. 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 Mn(1), and two equivalent Mn(2) atoms. In the fourth Ge site, Ge(5) is bonded in a 6-coordinate geometry to two equivalent Ti(1), two equivalent Mn(1), and two equivalent Mn(2) atoms.
