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
2013
Abstract 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 (Co II , Ni II and Zn II ) 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.
