摘要
合成了两种新的二茚镱苯甲酸衍生物:Ind_2YbOCOC_6H_4(O—OC_2H_5),Ind_2YbOCOC_6H_4(O—I).经过元素分析、红外光谱及质谱鉴定,确证他们为茚基、邻取代羧酸阴离子与镱的桥式配位二聚体结构,分子中苯甲酸阴离子的邻位取代基中的配位原子(O,I)与镱均有微弱络合作用.
Two new diindenyl ytterbium benzoate derivatives,namely,Ind_2YbOCOC_6H_4(O- C_2H_5),Ind_2YbOCOC_6H_4(O—I),were synthesized.These compounds were identified by elemental analy- sis,IR and MS,showing that they were dimers with o—substituted benzoate ions as bridging groups. It was found that,the donor atom(O,I)in the complexes slightly coordinated with ytterbium.
