Crystallographic and spectroscopic assessment of chelate-stabilized aryl halide complexes at a seven-coordinate d4 molybdenum centre

A new series of chelate stabilized aryl halide coordination complexes of molybdenum are prepared by a novel oxidative addition strategy; quantitative equilibrium measurements suggest that the structure of the chelate ring, rather than the identity of the halide (X = Cl, Br, I), controls the strength of aryl halide binding in these complexes.
