摘要
对镧、铈与环己基甲酸及 2 -乙基己酸的 5种配合物单晶进行了红外光谱分析 ,结果表明 ,配合物中的羧基可能采取双齿螯合、双齿桥式或三齿螯合桥式等配位形式。
The complexes of trivalent lanthanide (M=La,Ce) with cyclohexane carboxylic acid or 2-ethyl hexanoic acid,were characterized by IR spectroscopy in this paper.From the results of IR spectroscopy,there are the chelating,bridging and tridentate bridging carboxyl groups in these complexes.
