The tetrahedral cobalt(II) complexes A‐D are found to possess an unusual coordinately unsaturated nature. These additives significantly inhibit the thermal polymerization of acrylamide and further, they impart significant induction period during AIBN initiated polymerization of MMA and acrylamide. Some evidence has been obtained to show that the additives' effect plausibly results because of the reaction of the coordinately unsaturated cobalt complexes with radicals present in the system.
