Complexation of cyclohexadiene tricarbonyl iron with imidazolidine-2-thione. Crystal structural and antimicrobial activity studies of the tricarbonyl (1-4-η-5-N-imidazolidinio-2-thionecyclohexa-1,3-diene) iron labelled complex

The reaction of imidazolidine-2-thione C3H6N2S with tricarbonyl (1-4-η-5-N-pyridiniocyclohexa-1,3-diene) iron tetrafluoroborate [C14H12NFe(CO)3]+ BF4− is described. The crystal structure of tricarbonyl (1-4-η-5-N-imidazolidinio-2-thionecyclohexa-1,3-diene) iron complex is presented and discussed. The antimicrobial activity studies of the imidazolidine-2-thione and the labelled complex were performed and compared.
