The structure described by MnAlGe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Mn(1) is bonded to four equivalent Mn(1), four equivalent Al(1), and four equivalent Ge(1) atoms to form a mixture of distorted corner and face-sharing MnMn4Al4Ge4 cuboctahedra. Al(1) is bonded in a 9-coordinate geometry to four equivalent Mn(1) and five equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Mn(1) and five equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
