Oxovanadium(IV) complexes of the monosaccharides D- and L-arabinose, D-galactose, D-mannose, D-lyxose, D-xylose and the disaccharide maltose were obtained in aqueous solutions at pH 13. Their sodium salts were precipitated with absolute ethanol and characterized by UV-vis spectroscopy (absorption and reflectance), thermo-analytical (TG and DTA) data, magnetic susceptibility measurements and IR-spectroscopy. All the complexes were found to be mononuclear, possessing the VO2+ moiety. The IR spectra were analyzed and discussed in detail allowing one to determine the characteristics of the metal-to-ligand interactions.
在pH值为13的水溶液中制得了单糖D-阿拉伯糖、L-阿拉伯糖、D-半乳糖、D-甘露糖、D-来苏糖、D-木糖以及二糖麦芽糖的氧钒(IV)配合物。它们的钠盐用无水乙醇沉淀,并通过紫外-可见光谱(吸收和反射)、热分析(热重和差热分析)数据、磁化率测量以及红外光谱进行表征。发现所有配合物均为单核,含有VO2+部分。对红外光谱进行了详细分析和讨论,从而能够确定金属与配体相互作用的特征。
