Formation of a Uranium Trithiocarbonate Complex via the Nucleophilic Addition of a Sulfide-Bridged Uranium Complex to CS 2

The uranium (IV) /uranium (IV) μ-sulfide complex ( ( (Ad) ArO) (3) N) U (2) (μ-S) reacts with CS (2) to form the trithiocarbonate-bridged complex ( ( (Ad) ArO) (3) N) U (2) (μ-κ (2): κ (2) -CS (3) ). The trithiocarbonate complex can alternatively be formed in low yields from low-valent ( ( (Ad) ArO) (3) N) U (DME) through the reductive cleavage of CS (2).
