Materials Data on MnAlGe by Materials Project
MnAlGe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Mn is bonded in a 12-coordinate geometry to four equivalent Mn, four equivalent Al, and four equivalent Ge atoms. All Mn–Mn bond lengths are 2.75 Å. All Mn–Al bond lengths are 2.62 Å. All Mn–Ge bond lengths are 2.56 Å. Al is bonded in a 9-coordinate geometry to four equivalent Mn and five equivalent Ge atoms. There are one shorter (2.53 Å) and four longer (2.75 Å) Al–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to four equivalent Mn and five equivalent Al atoms.
