Y Ni Au Au
YNiAu2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one YNiAu2 cluster. Y(1) is bonded in a bent 150 degrees geometry to one Ni(1) and one Au(1) atom. The Y(1)-Ni(1) bond length is 0.56 Å. The Y(1)-Au(1) bond length is 0.34 Å. Ni(1) is bonded in a water-like geometry to one Y(1) and one Au(2) atom. The Ni(1)-Au(2) bond length is 1.06 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a single-bond geometry to one Y(1) atom. In the second Au site, Au(2) is bonded in a single-bond geometry to one Ni(1) atom.
