Materials Data on MnGeRh by Materials Project
MnRhGe crystallizes in the orthorhombic Ima2 space group. The structure is three-dimensional. there are three inequivalent Mn sites. In the first Mn site, Mn is bonded in a 11-coordinate geometry to six Rh and five Ge atoms. There are a spread of Mn–Rh bond distances ranging from 2.77–2.85 Å. There are a spread of Mn–Ge bond distances ranging from 2.65–2.84 Å. In the second Mn site, Mn is bonded in a 5-coordinate geometry to four Rh and five Ge atoms. There are two shorter (2.84 Å) and two longer (3.05 Å) Mn–Rh bond lengths. There are a spread of Mn–Ge bond distances ranging from 2.61–2.69 Å. In the third Mn site, Mn is bonded in a 11-coordinate geometry to six Rh and five Ge atoms. There are a spread of Mn–Rh bond distances ranging from 2.84–3.05 Å. There are a spread of Mn–Ge bond distances ranging from 2.64–2.71 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 10-coordinate geometry to six Mn and four Ge atoms. There are two shorter (2.49 Å) and two longer (2.50 Å) Rh–Ge bond lengths. In the second Rh site, Rh is bonded in a 8-coordinate geometry to five Mn and four Ge atoms. There are three shorter (2.48 Å) and one longer (2.50 Å) Rh–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to three Mn and six Rh atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to six Mn and three Rh atoms.
