A number of cobalt( II ) chloride complexes of pyridine/amine N 3 and N 4 donors have been prepared and structurally characterised. Even though they are paramagnetic, assignment of the 1 H NMR signals was possible in several cases. With the exception of tpa, which formed a cationic monochloride complex, all new complexes have cis ‐coordinated chlorides. Nevertheless, only the relatively rigid pyp ligands gave rise to (low) ethene polymerisation activity on activation with MAO. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
