Y In In Au
YAuIn2 crystallizes in the triclinic P1 space group. Y(1) is bonded in a 5-coordinate geometry to two equivalent Au(1), one In(1), and two equivalent In(2) atoms. There is one shorter (2.84 Å) and one longer (3.06 Å) Y(1)-Au(1) bond length. The Y(1)-In(1) bond length is 2.25 Å. There is one shorter (2.85 Å) and one longer (3.17 Å) Y(1)-In(2) bond length. Au(1) is bonded in a distorted single-bond geometry to two equivalent Y(1), one In(1), and one In(2) atom. The Au(1)-In(1) bond length is 1.54 Å. The Au(1)-In(2) bond length is 1.98 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 1-coordinate geometry to one Y(1), one Au(1), and one In(2) atom. The In(1)-In(2) bond length is 1.41 Å. In the second In site, In(2) is bonded in a 4-coordinate geometry to two equivalent Y(1), one Au(1), and one In(1) atom.
