Materials Data on Y6MnBi2 by Materials Project
Y6MnBi2 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded to two equivalent Mn and two equivalent Bi atoms to form a mixture of distorted edge and corner-sharing YMn2Bi2 tetrahedra. Both Y–Mn bond lengths are 2.91 Å. Both Y–Bi bond lengths are 3.27 Å. In the second Y site, Y is bonded in a 5-coordinate geometry to one Mn and four equivalent Bi atoms. The Y–Mn bond length is 3.30 Å. All Y–Bi bond lengths are 3.34 Å. Mn is bonded in a 9-coordinate geometry to nine Y atoms. Bi is bonded in a 9-coordinate geometry to nine Y atoms.
