8-Aminoquinoline and 2-aminopyridine trifluoromethyl-derived enaminone ligands and their Co(II), Ni(II) and Zn(II) metal complexes: Structural arrangements due to F⋯H interactions

Two tridentate trifluoromethylated enaminones derived from 8-aminoquinoline and 2-aminopyridine L1H and L2H have been designed as ligands and 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.
