Abstract
Two novel mononuclear Zn(II) complexes, [ZnL1Cl2] (1) (L1=( E)-3-(4-(2,2′:6′,2″-tripyridyl)-4′-styryl)-7-diethylaminocoumarin) and [ZnL2Cl2] (2) (L2=3-(4-(2,2′:6′,2″-tripyridyl)-4′-phenylimine)-7-diethylaminocoumarin), were obtained by the solvothermal method from ZnCl2 and coumarin-based terpyridine ligands. The complexes were characterized by spectroscopic methods and single-crystal X-ray diffraction. The Zn2+ in the complexes is coordinated by three nitrogen atoms of the terpyridine ligand and two chloride anions, forming a distorted trigonal bipyramidal environment. Moreover, the UV–Vis absorption and emission spectra of the ligands and complexes in diluted dichloromethane solutions were measured.
