Materials Data on YCdAu by Materials Project

YAuCd crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Y is bonded in a 11-coordinate geometry to five Au and six equivalent Cd atoms. There are four shorter (3.08 Å) and one longer (3.21 Å) Y–Au bond lengths. There are two shorter (3.24 Å) and four longer (3.42 Å) Y–Cd bond lengths. There are two inequivalent Au sites. In the first Au site, Au is bonded in a 9-coordinate geometry to three equivalent Y and six equivalent Cd atoms. All Au–Cd bond lengths are 2.84 Å. In the second Au site, Au is bonded in a 9-coordinate geometry to six equivalent Y and three equivalent Cd atoms. All Au–Cd bond lengths are 2.94 Å. Cd is bonded in a 4-coordinate geometry to six equivalent Y and four Au atoms.
