Abstract

The unprecedented spectroscopic and structural characterisation of a series of 17-electron, monometallic diynyl radicals, [Mo(C≡C–C≡CR)L2(η-C7H7)]˙+ (L2 = bipy, R = SiMe3; L2 = dppe, R = SiMe3 or H), are reported; the (L2 = dppe, R = SiMe3) derivative is reactive to chain-centred Cβ–Cβ′ dimerisation.
