| 摘 要： | 报道了具有强荧光的甲基苯甲酸铕与１，１０－二氮杂菲和甲基苯甲酸铕与２，２－联吡啶等形成的６个配合物的喇曼光谱。羧基阴离子的反对称伸缩振动（Ｖａｓ（ＣＯＯ））和对称伸缩振动（Ｖｓ（ＣＯＯ））谱带是带肩峰或明显分裂的宽带。喇曼光谱说明这类配合物中羧基同时存在多种配位方式，这与它们的晶体测定结果一致。振动光谱还说明Ｅｕ（ｍ－ＭＢＡ）２ＮＯ３ｐｈｅｎ和Ｅｕ（０－ＭＢＡ）２ＮＯ３ｐｈｅｎ配合物中硝酸根是双齿

| Abstract: | The Raman spectra of six europium methylbenzoate complexes with 1,10-phenanthroline and 2,2-bipyridyl which emit intensely red light are reported. Bands of antisymmetric and symmetric streching vibrations in the carboxylate anions are broad or significantly split. Raman spectra show more than one coordination modes for the carboxylate groups in the complexes. This is in agreement with structure determination of the title complexes. Vibrational spectra indicate that the nitrate anion in the Eu(m-MBA)2NO3phen and Eu(o-MBA)2NO3phen complexes is bidentate and the coordination modes of the central europium atom with carboxylate anions and 1,10-phenanthroline may be the same as other title complexes. |
