Triflate vs Acetonitrile: Understanding the Iron(II)-Based Coordination Chemistry of Tri(quinolin-8-yl)amine.

In this study, a synthesis route of tri(quinolin-8-yl)amine (), a recent member of the tetradentate tris(2-pyridylmethyl)amine (TPA) ligand family, is reported. With the neutral ligand bound to an iron(II) center in κ mode, two -oriented coordination sites remain vacant. These can be occupied by coligands such as counterions and solvent molecules.
