Materials Data on MnNi2Sb by Materials Project

Ni2MnSb crystallizes in the cubic F-43m space group. The structure is three-dimensional. Mn is bonded in a distorted body-centered cubic geometry to ten Ni and four equivalent Sb atoms. There are four shorter (2.61 Å) and six longer (3.02 Å) Mn–Ni bond lengths. All Mn–Sb bond lengths are 2.61 Å. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a 4-coordinate geometry to four equivalent Mn and four equivalent Ni atoms. All Ni–Ni bond lengths are 2.61 Å. In the second Ni site, Ni is bonded in a 4-coordinate geometry to six equivalent Mn, four equivalent Ni, and four equivalent Sb atoms. All Ni–Sb bond lengths are 2.61 Å. Sb is bonded in a distorted body-centered cubic geometry to four equivalent Mn and four equivalent Ni atoms.
