Cobalt analogs of the Roussin’s red salt esters have been prepared by the reaction of organic thiol or selenol compounds with the readily prepared [Co(NO) 2Cl] 2. The compounds are unstable to light and decompose in ca. 1 week even in the dark at −78 °C. The IR spectra suggest that the compounds have C 2 v symmetry with the possibility of a folded Co 2S 2 rhombus about the S–S axis.
