LaMnGe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. La(1) is bonded in a 9-coordinate geometry to four equivalent Mn(1) and five equivalent Ge(1) atoms. Mn(1) is bonded to four equivalent La(1) and four equivalent Ge(1) atoms to form a mixture of distorted face and edge-sharing MnLa4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to five equivalent La(1) and four equivalent Mn(1) atoms.
LaMnGe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. La(1) is bonded in a 9-coordinate geometry to four equivalent Mn(1) and five equivalent Ge(1) atoms.
