The material described by EuMnBi2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal I4/mmm space group. Eu(1) is bonded to four equivalent Mn(1), four equivalent Bi(1), and four equivalent Bi(2) atoms to form distorted EuMn4Bi8 cuboctahedra that share corners with eight equivalent Eu(1)Mn4Bi8 cuboctahedra, corners with eight equivalent Mn(1)Eu4Bi4 tetrahedra, edges with four equivalent Eu(1)Mn4Bi8 cuboctahedra, edges with four equivalent Mn(1)Eu4Bi4 tetrahedra, and faces with five equivalent Eu(1)Mn4Bi8 cuboctahedra. Mn(1) is bonded to four equivalent Eu(1) and four equivalent Bi(2) atoms to form distorted MnEu4Bi4 tetrahedra that share corners with eight equivalent Eu(1)Mn4Bi8 cuboctahedra, edges with four equivalent Eu(1)Mn4Bi8 cuboctahedra, edges with four equivalent Mn(1)Eu4Bi4 tetrahedra, and faces with four equivalent Mn(1)Eu4Bi4 tetrahedra. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to four equivalent Eu(1) and four equivalent Bi(1) atoms. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to four equivalent Eu(1) and four equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
