Materials Data on Ba(MnBi)2 by Materials Project
BaMn2Bi2 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 Bi atoms. All Ba–Bi bond lengths are 3.73 Å. Mn is bonded to four equivalent Bi atoms to form a mixture of edge and corner-sharing MnBi4 tetrahedra. All Mn–Bi bond lengths are 2.82 Å. Bi is bonded in a 4-coordinate geometry to four equivalent Ba and four equivalent Mn atoms.
