TiMnGe crystallizes in the orthorhombic Ima2 space group. There are three inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 4-coordinate geometry to one Ge(2) and four equivalent Ge(1) atoms. In the second Ti site, Ti(2) is bonded to two equivalent Ge(2) and four equivalent Ge(1) atoms to form distorted face-sharing TiGe6 square pyramids. In the third Ti site, Ti(3) is bonded in a 5-coordinate geometry to one Ge(2) and four equivalent Ge(1) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 4-coordinate geometry to two equivalent Ge(1) and two equivalent Ge(2) atoms. In the second Mn site, Mn(2) is bonded in a 4-coordinate geometry to two equivalent Ge(1) and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Ti(1), two equivalent Ti(2), two equivalent Ti(3), one Mn(2), and two equivalent Mn(1) atoms. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to one Ti(1), one Ti(3), two equivalent Ti(2), two equivalent Mn(2), and four equivalent Mn(1) atoms.
TiMnGe crystallizes in the orthorhombic Ima2 space group. There are three inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 4-coordinate geometry to one Ge(2) and four equivalent Ge(1) atoms. The Ti(1)-Ge(2) bond length is 2.90 Å. There are two shorter (2.64 Å) and two longer (2.70 Å) Ti(1)-Ge(1) bond lengths. In the second Ti site, Ti(2) is bonded to two equivalent Ge(2) and four equivalent Ge(1) atoms to form distorted face-sharing TiGe6 square pyramids. There is one shorter (2.65 Å) and one longer (3.08 Å) Ti(2)-Ge(2) bond length. There are two shorter (2.63 Å) and two longer (2.65 Å) Ti(2)-Ge(1) bond lengths.
