摘　　要：用二氯二茂钛乙酰丙酮的水溶液与５硝基水杨酸钠在不同条件下合成了２ 种配合物，通过ＩＲ 和１ＨＮＭＲ 的分析，结果表明水杨酸分别以单齿和双齿形式与钛配位，在双取代配合物结构中，两苯环对应质子不等价．Two complexes were prepared in different conditions by reaction of biscyclopentadienyl dichlorotitanium(Ⅳ) acetylacetone complex and sodium of 5 nitrosalicylic acid in aqueous medium. IR and 1 HNMR spectra of them were determined. Spectroscopic data suggest that the salicylic acid adopt monodentate or bidentate structure. The protons are matchless and unsymmetrical in the two benzene rings of bi substituted complex.
