【摘要】 测定并研究了单硫代二苯甲酰甲烷（ＨＴＤＢＭ）及其稀土配合物Ｌｎ（ＴＤＢＭ）４［（Ｃ２Ｈ５）２ＮＨ］Ｈ（Ｌｎ＝除Ｃｅ、Ｔｍ外的Ｌａ－Ｌｕ）的光电子能谱（ＸＰＳ）。结果表明：Ｌｎ３＋离子通过Ｏ原子和Ｓ原子配位形成螫合物，Ｌｎ—Ｏ键和Ｌｎ—Ｓ键均具有一定程度的共价性；从Ｌａ到Ｌｕ，配位键的离子性逐渐增强；观察到Ｌａ３＋配合物３ｄ５／２具有伴峰现象。更多还原

【Abstract】 The X-ray photoelectron spectra of monothicbenzoylmethane and its lanthanide cbelates Ln(TDBM)4 [(C2 H5)2 NH]H (Where Ln=La-Lu except Ce and Tin) are investigated. It is proved by the changes of binding energy that the Ln3+ions are coordinated through O atom and S atom, Ln-O bond and Ln-S bond have a Certain covalent character and the ion character of the coordinate bond becomes stronger from La to Lu. The 3d5/2 satellite phenomenon of La(Ⅲ) chelate is also observed.更多还原
