YWTe2 crystallizes in the trigonal R3m space group. Y(1) is bonded in a distorted single-bond geometry to one W(1), three equivalent Te(1), and three equivalent Te(2) atoms. The Y(1)-W(1) bond length is 2.44 Å. All Y(1)-Te(1) bond lengths are 3.12 Å. All Y(1)-Te(2) bond lengths are 3.03 Å. W(1) is bonded in a 2-coordinate geometry to one Y(1), one Te(2), and three equivalent Te(1) atoms. The W(1)-Te(2) bond length is 2.44 Å. All W(1)-Te(1) bond lengths are 3.03 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 7-coordinate geometry to three equivalent Y(1), three equivalent W(1), and one Te(2) atom. The Te(1)-Te(2) bond length is 2.44 Å. In the second Te site, Te(2) is bonded in a 5-coordinate geometry to three equivalent Y(1), one W(1), and one Te(1) atom.
