The synthesis, structural characterization, and reactivity of heavier metal polychalcogenide (i.e. polyselenide and polytelluride) compounds are currently an active area of research after intense studies on metal polysulfides in the last decade. Recently, the authors reported on the chemistry of silver-polyselenide complexes, a system characterized by great structural diversity. Furthermore, their preliminary exploration on the Au/Se{sub x}{sup 2{minus}} system revealed an intriguing and unanticipated redox chemistry. This interesting redox interplay between Au{sup n+} (n = 1,3) and Se{sub x}{sup 2{minus}} incited them to investigate further this system in order to gain more information and insight into the redox behavior of gold in the presence of Se{sub x}{sup 2{minus}} ligands. In order to influence the aforementioned redox chemistry, they examined the reactivity of AuCN toward less reducible shorter polyselenide Se{sub x}{sup 2{minus}} ligands (i.e. x = 1-4) in the presence of different counterions such as Ph{sub 4}P{sup +}, ((Ph{sub 3}P){sub 2}N){sup +}, Pr{sub 4}N{sup +}, etc. Here they wish to report the newly isolated (Ph{sub 4}P){sub 2}(Au{sub 2}(Se{sub 2})(Se{sub 3})) (I), ((Ph{sub 3}P){sub 2}N){sub 2}(Au{sub 2}(Se{sub 2})(Se{sub 3})) (II), and (Ph{sub 4}P){sub 2}(Au{sub 2}(Se{sub 2})(Se{sub 4})) (III), the first Au(I) polyselenide complexes isolated from solution.
