通过将配体直接连接到WOCl 4上,合成了基于三齿配体[O,N,O] -2-[(4-羟基-3-戊烯-2-亚烷基)氨基]酚(hpap)的新型钨配合物,导致从金属中心置换两个氯化物单元,并形成相应二氯化物络合物的顺式和反式异构体。通过X射线晶体学证实了顺式-[WOCl 2-(hpap)]的分子结构。合成的[WOCl 2-(hpap)],是顺式和反式的混合物异构体,已证明与三烷基铝作为助催化剂结合,可在环烯烃(如TCD和MCMT)的开环复分解聚合(ROMP)中形成高活性催化剂。然而,发现极性取代的单体复分解的有效性略低,这可能是由于单体极性基团与催化剂组分的相互作用所致。使用一维和二维1 H NMR和13 C NMR光谱对所得ROMP'd聚TCD的化学结构进行表征。

conductivity studies. Magnetic susceptibility measurements suggest antiferromagnetic exchange in binuclear Fe(III) and VO(IV) complexes. Thermo gravimetric analysis (TGA) provided unambiguous evidence for the presence of coordinated as well as lattice water in [VOL2(H2O)] · H2O. Cyclic voltammetric studies showed well-defined redox processes corresponding to Fe(III)/Fe(II) and VO(V)/VO(IV). In vitro

Abstract The syntheses and characterisation of several new anionic dioxo technetium(V) complexes containing dianionic tridentate and monoanionic bidentate Schiff base ligands are described. Complexes containing a sulphur donor atom as a functional group in these systems have a much lower OTO stretching frequency that is generally found for the trans-TcO 2 moiety. The complexes have been characterised
elemental analyses evidenced the formation of penta-coordinated monomeric species. The crystal structures of ligand H2L1 and complexes 1, 3 and 4 were determined by single crystal X-ray diffraction study. In the solid state, the ligand H2L1 exists as keto-enamine tautomeric form. There are N–H…O intra-molecular hydrogen bonds between amine and carbonyl groups. Diorganotin(IV) complexes 1, 3 and 4 are monomers

synthesized and characterized by physico-chemical and spectroscopic methods. The crystal structures of the complexes were determined by X-ray crystallography. In each of these complexes, the cobalt(III) centre has a slightly distorted octahedral environment, utilizing all available coordination centres of the ligands. The complexes were also screened for in vitro antibacterial activities against four
