The coordination chemistry of chiral NHC-oxazoline bidentate ligands was investigated with silver(I) and gold(I), yielding stable dinuclear cationic complexes in good yields via N-coordination the oxazoline heterocycle. After full characterization these complexes, reactivity homogeneous catalysis under oxidative conditions studied.

leptospirosis caused by infection with pathogenic leptospires, which is the most prevalent zoonotic disease in the world. the outer membrane proteins (omps) of pathogenic leptospires such as lipl41 play a crucial role in pathogenesis of this disease. therefore a major challenge to develop an effective vaccine against leptospirosis is application of basic research on the omps of leptospires to i...

The synthesis, spectroscopy and magnetic characterization of five new dinuclear copper(II) complexes are described. All five compounds have the general formula [Cu2(L)4(O-R)2](Cl)2 or [Cu2(L)2(Cl)2](Cl)2, in which R = CH3 or H, L=2, 3 or 4-pyridinemethanol as L2, L3 or L4, respectively. The title compounds consist of dinuclear units with bridging methoxo groups in [Cu2(L4)4(O-CH3)2](Cl)2, hydro...

A binuclear macrocyclic ligand containing dissimilar N(amine)2O2 and N(imine)2O2 coordination sites sharing two phenolic oxygen atoms, was prepared by cyclic condensation of dialdehyde precursor L1H2 with 1,3-diaminopropane. The ligand includes two propionitrile pendant arms on the amine nitrogen atoms. The homobimetallic com...

The angle defect, which is the standard way to measure the curvatures at the vertices of polyhedral surfaces, goes back at least as far as Descartes. Although the angle defect has been widely studied, there does not appear to be in the literature an axiomatic characterization of the angle defect. In this paper a characterization of the angle defect for simplicial surfaces is given, and it is sh...

The angle defect, which is the standard way to measure curvature at the vertices of polyhedral surfaces, goes back at least as far as Descartes. Although the angle defect has been widely studied, there does not appear to be in the literature an axiomatic characterization of the angle defect. We give a characterization of the angle defect for simplicial surfaces, and we show that variants of the...

The efficiency and performance of supported melamine/ copper complexes, S/[CuCl2(Mel)2].2MeOH, as a new adsorbent, for the adsorptive removal of Indigo Carmine (IC) from aqueous solutions, has been evaluated with respect to several experimental conditions including contact time, initial IC concentration, temperature and adsorbent dosage. The maximum removal pe...

Catalytic formation of borylamines from atmospheric N2 is achieved for the first time using a series homogenous (triphosphine)Mo complexes. Stepwise functionalization (triphosphine)Mo-nitrido complex with chloroborane led to synthesis imido complex. Electrochemical characterization (PPP)Mo-nitrido and (PPP)Mo-borylimido complexes showed that latter much more easily reduced.
