Pyridone derivatives carrying radical moieties were prepared, namely a nitronyl nitroxide derivative 5-(4′,4′,5′,5′- tetramethylimidazoline-3′-oxide-1′-oxyl)-2(1H)-pyridone (1) and a verdazyl derivative 1,5-dimethyl-3-[2(1H)-pyridone]-6-oxoverdazyl (2). In the solid state, 1 and 2 form, via N-H?O intermolecular hydrogen bonds between the pyridone moieties, a zigzag one-dimensional chain structure and a cyclic dimer structure, respectively. These compounds exhibit antiferromagnetic intermolecular interactions. Mononuclear metal complexes [M(hfac) 2(1)2] (M = CuII, MnII; hfac = bis(hexafluoroacetylacetonate)) were prepared in which trans-[M(hfac) 2] are coordinated with the carbonyl oxygen of the pyridone ligands. Cyclic hydrogen bonds between the mononuclear units result in the formation of one-dimensional chains. Small antiferromagnetic (for CuII) and ferromagnetic (for MnII) exchange interactions between the metal ion and the ligands were observed.
