“…Polysulfide anions (S n 2– ) are classic examples of the catenation property of sulfur and are quite well-known in the literature. ,− The synthesis, structural diversity, and reactivity of an appreciable number of mono-, bi-, and poly nuclear compounds of polysulfide involving transition metals, lanthanides, and main group elements have been reported previously. − It may, however, be noted that most of these metal–polysulfido compounds are strictly organometallic compounds. − ,− ,− ,,,, While reports on several binuclear transition metal-polysulfido compounds are available in the literature, ,,,− the majority of these compounds are, however, metal sulfides and clusters with only S-donor ligands (HS – , S 2– , and S n 2– ).
