Abstract

Photolysis of the manganese half‐sandwich complex (η⁵‐C₅Me₅)Mn(CO)₃ (1) in tetrahydrofuran (thf) cleanly yields the solvent complex (η⁵‐C₅Me₅)Mn(CO)₂(thf) (2). Compound 2 is stable as solid at temperatures well below 0°C but undergoes spontaneous elimination of carbon monoxide at ambient temperature with concomitant formation of the novel dinuclear complex (η⁵‐C₅Me₅)₂‐Mn₂(μ‐CO)₃ (3). While elemental analysis, infrared and mass spectroscopy as well as the ¹H NMR and ¹³C NMR spectra unequivocally demonstrate this compound to adopt a highly symmetrical triply carbonyl‐bridged structure, a single‐crystal X‐ray diffraction study supports the presence of the first triple bond between manganese atoms (dMn – Mn 217.0(1) pm). An improved synthesis of tricarbonyl(η⁵‐pentamethylclopentadienyl)manganese (1) is also described.
