8-羟基喹啉-N-氧化物和5,7-二硝基-8-羟基喹啉-N-氧化物与Au(Ⅲ)、Pd(Ⅱ)的配合物之合成

Syntheses of Gold(Ⅲ)and Palladium(Ⅱ) Complexes with 8-Quinolinol-N-Oxide and 5, 7-Dinitro-8-Quinolinol-N-Oxide

合成4种标题配合物,用元素分析、红外和紫外光谱、摩尔电导、核磁共振氢谱、荧光光谱及X射线粉末衍射物相分析研究了它们的组成和性质及其结构。按结构将配合物分为两类,一是含氢键的离子缔合物;一是含金属—氧键的螯环型配合物。

Four solid complexes of gold(Ⅲ) and palladium(Ⅱ)with 8-quinolinol-N-oxide and its disubstituted derivation 5, 7-dinitro-8-quinolinol-N-oxide are synthesized for the first time. Their compositions and properties have been determined by elemental analysis, IR, UV, H-NMR and fluorescence spectra, molar conductance and X-ray powder diffraction. Their molecular structures are discussed too. These complexes can be classified as two types. One is the ion-associated compounds containing hydrogen bond(complex I). The other is the six-membered metal chelates containing metal-oxygen bonds (complexes Ⅱ—Ⅳ).
