A new family of Cs- and C1-symmetric 2,6-bis(imino)pyridyl ligands has been synthesised. These ligands, which differ from their known counterparts in the contemporaneous presence of alkyl and aryl substituent at the ketimine nitrogen atoms, form stable, five-coordinate complexes with FeCl2 and COC12. All ligands and catalysts have been fully characterised both in the solid state and in solution. A single-crystal X-ray analysis of [CoCl2-{2-[CMe=N-(2,6- dimethylphenyl)]6-(CMe=N-C6H11)C5H3 N}]·H2O shows the metal centre to adopt a highly distorted square-pyramidal geometry. In combination with methylaluminoxane (MAO), both iron and cobalt compounds act as effective and selective (> 99%) catalysts for the oligomerisation of ethylene to a Schulz-Flory distribution of α-olefins, with the α factor ranging from 0.61 to 0.91. The iron catalysts exhibit TOFs as high as 7.105 mol C2H4 (mol of cat × h)-1 and are much more active than their cobalt analogues. Experiments at different ethylene pressures with the iron catalysts showed that both the propagation rate and the chain transfer rate are first order in ethylene pressure.
