TmMnGe crystallizes in the orthorhombic Pnma space group. Tm(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. Mn(1) is bonded in a 4-coordinate geometry to four equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to five equivalent Tm(1) and four equivalent Mn(1) atoms.
TmMnGe crystallizes in the orthorhombic Pnma space group. Tm(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. There are two shorter (2.91 Å) and three longer (2.94 Å) Tm(1)-Ge(1) bond lengths. Mn(1) is bonded in a 4-coordinate geometry to four equivalent Ge(1) atoms. There are a spread of Mn(1)-Ge(1) bond distances ranging from 2.54-2.74 Å. Ge(1) is bonded in a 9-coordinate geometry to five equivalent Tm(1) and four equivalent Mn(1) atoms.
