Materials Data on MnAsRh by Materials Project
MnRhAs crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Mn is bonded in a 10-coordinate geometry to six equivalent Rh and four As atoms. There are four shorter (2.79 Å) and two longer (2.82 Å) Mn–Rh bond lengths. There are two shorter (2.46 Å) and two longer (2.57 Å) Mn–As bond lengths. Rh is bonded in a 11-coordinate geometry to six equivalent Mn and five As atoms. There are one shorter (2.53 Å) and four longer (2.70 Å) Rh–As bond lengths. There are two inequivalent As sites. In the first As site, As is bonded in a 9-coordinate geometry to six equivalent Mn and three equivalent Rh atoms. In the second As site, As is bonded in a distorted trigonal planar geometry to three equivalent Mn and six equivalent Rh atoms.
