The structure described by BaMn2Bi2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a body-centered cubic geometry to eight equivalent Bi(1) atoms. Mn(1) is bonded to four equivalent Bi(1) atoms to form a mixture of edge and corner-sharing MnBi4 tetrahedra. Bi(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
