Y Y Y Y Cr Te
Y4CrTe crystallizes in the trigonal R3m space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 4-coordinate geometry to one Y(2), two equivalent Y(1), one Cr(1), and one Te(1) atom. The Y(1)-Y(2) bond length is 2.43 Å. Both Y(1)-Y(1) bond lengths are 1.41 Å. The Y(1)-Cr(1) bond length is 2.78 Å. The Y(1)-Te(1) bond length is 2.49 Å. In the second Y site, Y(2) is bonded in a 6-coordinate geometry to three equivalent Y(1) and three equivalent Te(1) atoms. All Y(2)-Te(1) bond lengths are 3.60 Å. Cr(1) is bonded in a trigonal pyramidal geometry to three equivalent Y(1) and one Te(1) atom. The Cr(1)-Te(1) bond length is 2.92 Å. Te(1) is bonded in a 7-coordinate geometry to three equivalent Y(1), three equivalent Y(2), and one Cr(1) atom.
