Since our finding that the hexanuclear rhenium selenide cluster core activates nitriles to undergo various cyclization reactions, we have been interested in studying how these octahedral [M6X8]n+ cores influence the reactivity of coordinated ligands. Initial studies focused on coordinated nitriles undergoing reaction with NaN3, hydroxide and haloalcohols. More recently, we have been able to coordinate the azide ion to the rhenium selenide core, forming [Re6Se8(PEt3)5(N3)](BF4), and cis-[Re6Se8(PEt3)4(N3)2]. This presentation will concentrate on the synthesis and reactivity of these cluster complexes. Reaction of the coordinated azides with activated alkynes to form triazolate ligands will be discussed along with other reactivity studies.
