Materials Data on Cr4Ni by Materials Project
Cr4Ni crystallizes in the orthorhombic Fmmm space group. The structure is three-dimensional. there are two inequivalent Cr sites. In the first Cr site, Cr is bonded in a 8-coordinate geometry to two equivalent Cr and two equivalent Ni atoms. Both Cr–Cr bond lengths are 2.48 Å. Both Cr–Ni bond lengths are 2.46 Å. In the second Cr site, Cr is bonded in a distorted body-centered cubic geometry to eight Cr atoms. There are four shorter (2.44 Å) and two longer (2.50 Å) Cr–Cr bond lengths. Ni is bonded in a 12-coordinate geometry to four equivalent Cr atoms.
