The synthesis and characterization of several mono- and di-substituted bis(diarene)chromium-[tricarbonylchromium] complexes is described, where the diarene is a biphenyl-like ligand. A number of carbon based groups incorporating different hydridizations are used as spacers between the π-coordinated rings in the diarene moiety. The effect of the spacing group upon the inductive and resonance effects
