Crystal structure and insulin-like activity of a vanadium complex derived from N′-(3,5-dichloro-2-hydroxybenzylidene)-2-methylbenzohydrazide
摘要:
Vanadium complexes have been proved to possess an interesting insulin-like activity. The reaction of VO(acac)(2) with N'-(3,5-dichloro-2-hydroxybenzylidene)-2-methylbenzohydrazide (H2L) in methanol affords a new mononuclear vanadium (V) complex [VOL(OMe)(MeOH)]. The structure of the complex is characterized by physicochemical methods and single crystal X-ray diffraction. The complex crystallizes as the monoclinic space group P2(1)/n, with unit cell parameters a = 7.830(2) , b = 23.225(3) , c = 10.635(2) , beta = 101.947(2)A degrees, V = 1892.1(6) (3), Z = 4, R (1) = 0.0404, wR (2) = 0.0953, S = 1.037. The X-ray analysis indicates that the V atom in the complex is in the octahedral coordination. The insulin-like activity of the complex is studied.

New dioxidomolybdenum(VI) complexes with the formula [MoO 2 L(MeOH)], derived from N' -(5-chloro-2-hydroxybenzylidene)-2-methylbenzohydrazide (H 2 L 1 ) and N' -(3,5-dichloro-2-hydroxybenzylidene)-2-methylbenzohydrazide (H 2 L 2 ) were prepared. Crystal and molecular structures of the complexes were determined by single crystal X-ray diffraction method. Both complexes were further characterized by
由N'-(5-氯-2-羟基苄叉基)-2-甲基苯并酰肼(H 2 L 1)和N'-(3,5)衍生的具有式[MoO 2 L(MeOH)]的新型二氧化钼(VI)配合物制备了-二氯-2-羟基亚苄基)-2-甲基苯并酰肼(H 2 L 2)。通过单晶X射线衍射法确定配合物的晶体和分子结构。两种配合物都通过元素分析和FT-IR光谱进一步表征。单晶X射线结构研究表明,L 1和L 2通过烯醇氧,酚氧和偶氮甲碱氮与MoO 2核配位。两个络合物中的Mo原子均为八面体配位。已经研究了使用PhIO和NaOCl作为氧化剂的配合物对苯乙烯环氧化的催化性能。
