Abstract

BaMnBi2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Ba sites. In the first Ba site, Ba is bonded to four Mn and eight Bi atoms to form distorted BaMn4Bi8 cuboctahedra that share corners with eight equivalent BaMn4Bi8 cuboctahedra, corners with eight MnBa4Bi4 tetrahedra, edges with four equivalent BaMn4Bi8 cuboctahedra, edges with four MnBa4Bi4 tetrahedra, and faces with five equivalent BaMn4Bi8 cuboctahedra. All Ba–Mn bond lengths are 3.91 Å. There are four shorter (3.69 Å) and four longer (3.70 Å) Ba–Bi bond lengths. In the second Ba site, Ba is bonded to four Mn and eight Bi atoms to form distorted BaMn4Bi8 cuboctahedra that share corners with eight equivalent BaMn4Bi8 cuboctahedra, corners with eight MnBa4Bi4 tetrahedra, edges with four equivalent BaMn4Bi8 cuboctahedra, edges with four MnBa4Bi4 tetrahedra, and faces with five equivalent BaMn4Bi8 cuboctahedra.
