Materials Data on Mn2GaRh by Materials Project

Mn2RhGa crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Mn sites. In the first Mn site, Mn is bonded to four equivalent Mn and four equivalent Rh atoms to form distorted edge-sharing MnMn4Rh4 tetrahedra. All Mn–Mn bond lengths are 2.59 Å. All Mn–Rh bond lengths are 2.59 Å. In the second Mn site, Mn is bonded in a 4-coordinate geometry to four equivalent Mn, six equivalent Rh, and four equivalent Ga atoms. All Mn–Rh bond lengths are 2.99 Å. All Mn–Ga bond lengths are 2.59 Å. Rh is bonded in a distorted body-centered cubic geometry to ten Mn and four equivalent Ga atoms. All Rh–Ga bond lengths are 2.59 Å. Ga is bonded in a distorted body-centered cubic geometry to four equivalent Mn and four equivalent Rh atoms.
