Abstract: Copolymerization of potassium - and -bis[N-(5-methacryloylamino)salicylidene-(S)-norvalinato]-cobaltate(III) (1 and 2) with acrylamide and N,N-methylenediacrylamide gives crosslinked gels. The behaviour of the amino acid moiety in the gel obtained from the isomer with the (S,S) configuration does not differ from that of the monomeric model compound 4. The (S,S) isomer gives gels, in which a part of the complex proves to be attached by both phenyl moieties to one polymeric chain forming a macrocycle. Deuterium exchange in such complexes proceeds with full retention of the configuration of the amino acid
