Materials Data on Ba(MnGe)2 by Materials Project
BaMn2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ba is bonded in a distorted body-centered cubic geometry to eight equivalent Ge atoms. All Ba–Ge bond lengths are 3.53 Å. Mn is bonded to four equivalent Ge atoms to form a mixture of distorted edge and corner-sharing MnGe4 tetrahedra. All Mn–Ge bond lengths are 2.48 Å. Ge is bonded in a 4-coordinate geometry to four equivalent Ba and four equivalent Mn atoms.
