In the second Os site, Os(2) is bonded in a single-bond geometry to one Os(3), one Os(4), and one Te(2) atom. The Os(2)-Os(3) bond length is 2.49 Å. The Os(2)-Os(4) bond length is 1.75 Å. The Os(2)-Te(2) bond length is 0.99 Å. In the third Os site, Os(3) is bonded in a 5-coordinate geometry to one Os(1), one Os(2), one Os(4), one Te(1), and one Te(2) atom. The Os(3)-Os(4) bond length is 1.91 Å. The Os(3)-Te(1) bond length is 2.96 Å. The Os(3)-Te(2) bond length is 2.78 Å. In the fourth Os site, Os(4) is bonded in a 4-coordinate geometry to one Os(1), one Os(2), one Os(3), and one Te(3) atom. The Os(4)-Te(3) bond length is 2.73 Å. There are three inequivalent Te sites.
