吡啶二甲酸镓、铟配合物的合成及生物活性

吡啶二甲酸能与过渡、非过渡、镧系和锕系金属离子螯合形成稳定的配合物，而且配位方式不拘一格，既可以是双齿，三齿，也可以是桥式配位。吡啶二甲酸的另一重要意义在于它们的生物活性。由于镓具有抗癌，抗肿瘤的活性，吡啶二甲酸镓配合物可能会是一种非常有潜力的新型药物。基于上述事实，本文合成了六种新型的吡啶二甲酸（2，3-，2，5-，2，6-）镓（Ⅲ）、铟（Ⅲ）配合物，并进一步测试了三种镓配合物的生物活性。     

呋喃甲醛缩二乙撑三胺希夫碱铜配合物的合成及结构(英)

A novel copper(Ⅱ) complex CuL(NO₃)₂(where L=N,N′-bis(furaldehyde)-diethylenetriamine) was synthesized and characterized by X-ray crystallography analysis. The crystal belongs to monoclinic, space group C2/c with cell parameters a=1.924 0(6) nm, b=0.792 8(3) nm, c=2.504 1(8) nm, β=111.163(5)°, and Z=8. The coordination geometry around Cu(Ⅱ) is a distorted trigonal-bipyramid，and one-dimensional chain is formed through intermolecular hydrogen bonds. CCDC: 255629.     

Vanadyl salen complexes covalently anchored to an imidazolium ion as catalysts for the cyanosilylation of aldehydes in ionic liquids

Two vanadyl salen complexes having peripheral styryl substituents have been reacted with 1-methyl-3-(3-mercaptopropyl)-imidazolium chloride using azoisobutyronitrile as radical initiator. The resulting compounds contain at the same time a vanadyl salen complex and one imidazolium cation. In agreement with the expectations in view of their structure, these compounds were insoluble in conventional organic solvents, but completely miscible in imidazolium ionic liquids. These vanadyl salen complexes bonded to an imidazolium cation are highly active and reusable catalysts for the cyanosilylation of aldehydes. Moderate enantiomeric excesses were obtained using the chiral version of this complex.     

Studies of a new series of ion-pair complexes [Mo(dtc)_4][Ln(dtc)_4] (Ln=La-Er,exp.Pm)

A new series of ion-pair complexes [Mo(dtc)4][Ln(dtc)4] (Ln=La-Er, exp. Pm) were synthesized from MoCl5, LnCl3 and Nadtc in anhydrous methanol. The crystal structures of the four complexes, [Mo(dtc)4][Ln(dtc)4] (Ln=Nd, Sm, Ho and Er) have been determined by X-ray diffraction. Spectroscopic properties of all these complexes are also discussed here.
