Materials Data on CrCu4NiSn2 by Materials Project
CrNiCu4Sn2 is Tungsten-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Cr is bonded in a distorted body-centered cubic geometry to eight Cu atoms. All Cr–Cu bond lengths are 2.68 Å. Ni is bonded in a distorted body-centered cubic geometry to eight Cu atoms. There are two shorter (2.63 Å) and six longer (2.66 Å) Ni–Cu bond lengths. There are three inequivalent Cu sites. In the first Cu site, Cu is bonded in a distorted body-centered cubic geometry to three equivalent Cr, one Ni, and four equivalent Sn atoms. There are three shorter (2.66 Å) and one longer (2.69 Å) Cu–Sn bond lengths. In the second Cu site, Cu is bonded in a distorted body-centered cubic geometry to one Cr, three equivalent Ni, and four equivalent Sn atoms. There are one shorter (2.62 Å) and three longer (2.67 Å) Cu–Sn bond lengths. In the third Cu site, Cu is bonded in a distorted body-centered cubic geometry to one Cr, three equivalent Ni, and four equivalent Sn atoms. There are one shorter (2.62 Å) and three longer (2.67 Å) Cu–Sn bond lengths. Sn is bonded in a distorted body-centered cubic geometry to eight Cu atoms.
