铕－邻菲罗啉－甲基苯甲酸二、三元配合物的NMR研究

NMR STUDES OF BINARY AND TERNARY COMPLEXES FOR Eu WITH 1,10-PHENANTHROLINE AND METHYLBENZOIC ACID

本文报道了希土铕（Ｅｕ３＋）与甲基苯甲酸（包括邻位０－ＭＢＡ．间位ｍ—ＭＢＡ，对位ｐ－ＭＢＡ）及邻菲罗咐（Ｐｈｅｎ）形成的二元和三元固体配合物的制备，对它们进行了元素分析，确定该配合物的组成为：二元：Ｅｕ（ＣＨ３Ｃ６Ｈ５ＣＯＯ）３，三元：Ｅｕ（ｐｈｅｎ）（ＣＨ３Ｃ６Ｈ５ＣＯＯ）３．对上述配合物的结构作了核磁共振氢谱（１ＨＮＭＲ）和碳谱（１３ＣＮＭＲ）的研究，并用红外光谱（ＩＲ）作了进一步确定．

inary and ternary solidified complexes of rare earth Bu3+ with methylbenzoic acid (including o-methylbenzoic acid, m-methylbenzoic acid, p-methylbenzoic acid) and1,10-phenanthroline were prepared in this article. Their compositions were confirmed by elemental analysis as: binary Eu(CH3C6H5COO)3, ternary Eu(phen) (CH3C6H5COO)3. Their structures were studied'with 1H, 13CNMR spectra. And, their structures were supported further byIR spectrum.
