Photolysis under nitrogen of toluene solutions of mixtures of tricarbonyl(η6-hexaethylbenzene)chromium(0), (1), and diphenylacetylene gave dicarbonyl(dinitrogen)(η6-hexaethylbenzene)chromium(0), (2), and μ-dinitrogen-bis6-hexaethylbenzene)chromium(0)>, (3), as the only identifiable organometallic products.A decoalescence phenomenon observed in the 90.56 MHz 13C-solution n.m.r. spectrum of (3) is attributed to slowed ethyl group rotation and a barrier (ΔG300) of 46.0+/-3.0 kJ mol-1 for this process has been determined and the molecule shown to be a dinitrogen-bridged dinuclear chromium complex with C2h molecular symmetry.The co-ordinated Hexaethylbenzene has been found to adopt a 1,3,5-distal-2,4,6-proximal methyl conformation.
