of nitronyl nitroxide ligands, two ligands substituted with quinoxaline (L1) and 2-phenyl-1, 2, 3-triazole (L2) and their NiII and ZnII complexes: Ni(L1)(hfac)2 (1), Ni(L2)(hfac)2 (2), and Zn(L2)(hfac)2 (3) (hfac = hexafluoroacetylacetonate), were synthesized and characterized. X-ray single-crystal diffraction analysis shows that compound 1 has a mononuclear structure, which is further linked into a
为了探索硝酰基氮氧化物配体的配位能力,两个被喹喔啉 (L1) 和 2-苯基-1, 2, 3-三唑 (L2) 取代的配体及其 NiII 和 ZnII 配合物:Ni(L1)(hfac)2 (1 )、Ni(L2)(hfac)2 (2) 和 Zn(L2)(hfac)2 (3)(hfac = 六氟乙酰丙酮化物)被合成并表征。X射线单晶衍射分析表明,化合物1具有单核结构,进一步通过C–H…F氢键连接成三维(3D)超分子网络,C–H…π , 和 π……π 叠加相互作用。配合物 2 和 3 具有相似的单核结构,通过各种分子间弱相互作用,如 C–H…F 氢键和 π…π 堆积相互作用,进一步连接成一维(1D)超分子链。结果表明,L1 和 L2 的空间体积以及六氟乙酰丙酮化物 (hfac) 的存在在控制配合物 1-3 最终框架的形成方面起着重要作用。此外,还详细研究了配体及其配合物的发光特性。
