Iron and cobalt mononitrosyls with schiff base co-ligands / Hadariah Bahron
The ligand N-4-methoxybenzylsalicylideneimine (MeObsal) is reacted with Fe2+ and Co2+ions separately. Both the systems are then reacted with nitric oxide (NO) to form two different complexes which are bis(N-4-methoxybenzylsalicylideneiminato)nitrosyliron, [Fe(MeObsal)2NO]; and bis(N-4-methoxybenzyls...
