Synthesis and Characterization of Pyrroles

Two tridentate trifluoromethylated enaminones derived from 8-aminoquinoline and 2-aminopyridine L1H and L2H have been designed as ligands that can exhibit multiple coordination centers. Five new complexes 1–5 based on transition metals (CoII, NiII and ZnII) were prepared and their crystal structure and redox properties have been studied. The role of the trifluoromethyl moieties and their ability to form F⋯H intra- and inter-complexes bonds leading to multidimensional networks have been also featured.
