(Y)3Y2Bi is black P-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Y cluster and one Y2Bi cluster. In the Y cluster, there are three inequivalent Y sites. In the first Y site, Y(2) is bonded in a distorted single-bond geometry to one Y(3) atom. The Y(2)-Y(3) bond length is 1.27 Å. In the second Y site, Y(3) is bonded in a bent 120 degrees geometry to one Y(2) and one Y(4) atom. The Y(3)-Y(4) bond length is 0.44 Å. In the third Y site, Y(4) is bonded in a single-bond geometry to one Y(3) atom. In the Y2Bi cluster, there are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a distorted single-bond geometry to one Y(5) and one Bi(1) atom. The Y(1)-Y(5) bond length is 1.06 Å. The Y(1)-Bi(1) bond length is 0.78 Å. In the second Y site, Y(5) is bonded in a 2-coordinate geometry to one Y(1) and one Bi(1) atom. The Y(5)-Bi(1) bond length is 1.25 Å. Bi(1) is bonded in a distorted single-bond geometry to one Y(1) and one Y(5) atom.
