Abstract

A bent manganese-tellurium-manganese framework exhibiting multiple bond character has been constructed by treatment of the solvent-stabilized organomanganese complex (η⁵-C₅Me₅)Mn(CO) ₂thf (1; thf = tetrahydrofuran) with aluminium telluride in the presence of aqueous hydrochloric acid; the dinuclear product (μ-Te)[(η⁵-C₅Me₅)Mn(CO) ₂]₂ (2) isolated in 46% yield has been shown by X-ray crystallography to contain a central 'bare' tellurium bridging atom which is attached to two independent (η⁵-C₅Me ₅)Mn(CO)₂ moieties via very short Te-Mn bonds [245.9(2) pm]; this compound reacts readily with diazoalkanes to give μ-alkylidene complexes of composition (μη²-TeCR₂) [(η⁵-C₅Me₅)Mn(CO)₂]₂ [(3a) R = H, (3b) R = Me].
