Materials Data on Er6MnBi2 by Materials Project
Er6MnBi2 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded to two equivalent Mn and two equivalent Bi atoms to form a mixture of distorted edge and corner-sharing ErMn2Bi2 tetrahedra. Both Er–Mn bond lengths are 2.87 Å. Both Er–Bi bond lengths are 3.24 Å. In the second Er site, Er is bonded in a 5-coordinate geometry to one Mn and four equivalent Bi atoms. The Er–Mn bond length is 3.21 Å. All Er–Bi bond lengths are 3.32 Å. Mn is bonded in a 9-coordinate geometry to nine Er atoms. Bi is bonded in a 9-coordinate geometry to nine Er atoms.
