Abstract
A complex of a tetradentate tetraanionic ligand L of the formula: ##STR1## and a metal, preferably a transition metal, is described. The chelate and ring Z-CH-M-Z functional groups Z, such as N or O are resistant to oxidation and the ring contains 4 to 7 preferably 5 to 6 chain atoms. An osmium complex containing two pyridine ligands is an oxidation catalyst. Further activation by anodic oxidation and heating to a temperature exceeding 30.degree. C. greatly increases catalytic activity.
