Multidentate complexes of group (6) metals such as chromium, molybdenum and tungsten comprising ligands capable of forming at least two electron donor bonds and at least one further single atom to single atom bond (e.g. a covalent sigma bond, a covalent pi bond or a carbene:metal bond) are useful as catalysts and components of catalyst systems for olefin polymerisation reactions.
