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.

新型香豆素三联吡啶配体及其Zn(II)配合物的合成与表征

两种新型单核 Zn(II) 配合物 [ZnL1Cl2] (1) (L1=(E)-3-(4-(2,2':6',2″-tripyridyl)-4'-styryl)-7-二乙基氨基香豆素)和[ZnL2Cl2](2)(L2=3-(4-(2,2':6',2"-三吡啶基)-4'-苯基亚胺)-7-二乙基氨基香豆素),通过溶剂热法从ZnCl2 和基于香豆素的三联吡啶配体。通过光谱方法和单晶 X 射线衍射对配合物进行了表征。配合物中的 Zn2+ 由三联吡啶配体的三个氮原子和两个氯阴离子配位,形成扭曲的三角双锥环境。此外,还测量了稀释二氯甲烷溶液中配体和配合物的紫外-可见吸收和发射光谱。
