The trichromium cluster (tbsL)Cr3(thf) ([tbsL]6–=[1,3,5-C6H9(NC6H4-o-NSitBuMe2)3]6–) exhibits steric- and solvation-controlled reactivity with organic azides to form three distinct products: reaction of (tbsL)Cr3(thf) with benzyl azide forms a symmetrized bridging imido complex (tbsL)Cr3(μ3-NBn); reaction with mesityl azide in benzene affords a terminally bound imido complex (tbsL)Cr3(μ1-NMes); whereas the reaction with mesityl azide in THF leads to terminal N-atom excision from the azide to yield the nitride complex (tbsL)Cr3(μ3-N). We report the reactivity of this complex demonstrates the ability of the cluster-templating ligand to produce a well-defined polynuclear transition metal cluster that can access distinct single-site and cooperative reactivity controlled by either substrate steric demands or reaction media.
