    • Despite many attempts, with different solvents and reducing agents, we have not been able to isolate 2a or 2b. Similar difficulties with other monofunctional 1,2,3-dithiazolyls, and their selenium analogues, have been encountered before, although the naphthalene version of 2a has been structurally characterized see ref 14

    • + is remarkably robust (air stable). Its infrared spectrum is strong, reproducible and not that of elemental tellurium; it also provided a good powder X-ray diffraction pattern. While we were unable to index this pattern, it was certainly not that of elemental tellurium.
