title: Materials Data on CrFeCoNi by Materials Project

description: CrFeCoNi is beta-derived structured and crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are two inequivalent Cr sites. In the first Cr site, Cr is bonded to four Fe, four Co, and four Ni atoms to form CrFe4Co4Ni4 cuboctahedra that share corners with two equivalent CrFe4Co4Ni4 cuboctahedra, corners with four equivalent FeCr4Fe2Co2Ni4 cuboctahedra, corners with twelve NiCr4Fe2Co4Ni2 cuboctahedra, edges with two equivalent NiCr4Fe2Co4Ni2 cuboctahedra, edges with four equivalent CoCr4Fe2Co2Ni4 cuboctahedra, edges with six CrFe4Co4Ni4 cuboctahedra, edges with six FeCr4Fe2Co4Ni2 cuboctahedra, faces with four FeCr4Fe2Co4Ni2 cuboctahedra, faces with four NiCr4Fe2Co4Ni2 cuboctahedra, faces with six CrFe4Co4Ni4 cuboctahedra, and faces with six CoCr4Fe4Co2Ni2 cuboctahedra. There are a spread of Cr–Fe bond distances ranging from 2.47–2.56 Å. There are two shorter (2.48 Å) and two longer (2.49 Å) Cr–Co bond lengths. There are a spread of Cr–Ni bond distances ranging from 2.51–2.53 Å.
