Abstract

Photolysis of the manganese half-sandwich complex (η⁵-C₅Me₅)Mn(CO)₃ (1) in tetrahydrofuran (THF) yields cleanly the solvent complex (η⁵-C₅Me₅)(Mn(CO)₂THF (2). Compound 2 undergoes spontaneous elimination of carbon monoxide to give at ambient temperature in approx. 20 h, or upon removal of solvent in vacuo, the novel dinuclear derivative (η⁵-C₅Me₅)₂Mn₂(μ-CO)₃ (3). Elemental analyses and infrared and mass as wel as the ¹H and ¹³C NMR spectra unequivocally demonstrate this compound to adopt a triply carbonyl-bridged structure containing the first example of a manganesemanganese multiple bond.
