Synthesis and Crystal Structure of Metal Complexes Based on 2,6-bis(6-Methylquinolin-2-yl)pyridine Ligand

摘要

Two mononuclear five-coordinated transition metal complexes FeLCl2 (I) and MnLCl2 (II) containing tridentate 2,6-bis(6-methylquinolin-2-yl)pyridine ligand (L) have been synthesized and characterized by single-crystal X-ray crystallography. In the complexes, the metal center was tridentately chelated by ligand and further coordinated by two chlorine atoms, resulting in distorted trigonal-bipyramidal geometry for complex I and II, respectively. In addition, crystal packing in complex is stabilized by C—H···Cl intermo-lecular hydrogen bond, which link the mononuclear complex to the 1D chain.
