The potency of the first-row transition metal complexes with Schiff's base ligand as an antioxidant has been widely studied by researchers. In this study, hydrazone-type Schiff base compounds, salicylaldehyde-2,4-dinitrophenylhydrazone (SDPH), resulted fr... see more

Rice husk ash (RHA) was used to prepare sodium silicate, which in turn was functionalized with 3-(chloropropyl)triethoxysilane employing the sol-gel technique to form RHACCl. Chloro group in RHACCl was replaced with iodo group forming RHACI. Ethylenediami... see more

Nickel(II) and copper(II) mixed-ligand complexes of Salicylaldehyde with 2,2'-bipyridine, 1,10-phenanthroline and ethylenediamine were synthesised and characterised by molar conductance, spectroscopic measurement, room temperature magnetic measurement and... see more

BSOPD, bis(salicylaldehyde) orthophenylenediamine) is investigated as complexing agent in capillary electrophoresis for determination of gold and chromium. BSOPD was chosen as the UV-Visible absorbing chelating ligand because of its ability to form stable... see more

Four Fe(III) spin-crossover (SCO) compounds, [Fe(HL1)2](HCl4TPA) (1-Cl), [Fe(HL1)2](HBr4TPA) (1-Br), [Fe(HL2)2](HCl4TPA) (2-Cl), and [Fe(HL2)2](HBr4TPA) (2-Br) (HL1 = 4-chloro-2-nitro-6-(1-(2-(pyridine-2-yl)hydrazono)ethyl)phenolate; HL2 = 4-bromo-2-nitro... see more

This study involves the preparation of seven new compounds, some of them contain two functional groups that are considered condensation monomers. On the other hand, other compounds contain double bonds that are considered addition monomers. They started f... see more

Synthesis of three Schiff bases of 5-bromo-3-nitro salicylaldehyde containing different sulfonamide group antibiotic compounds and their Cu(II) complexes was carried out. Structures of all compounds were characterized with spectroscopic methods, including... see more

Aim. To study the Host-Guest complexation of octakis(diphenoxyphosphoryloxy)-tetramethylcalix[4]resorcinarene (PRA), 5,17-bis(N-tolyl-iminomethyl)-25,27-dipropoxycalix[4]arene (IC4A), 5,11,17,23-tetrakis(diisopropoxyphosphonyl)-25,26,27,28-tetra-propoxyca... see more

O-3-X-5-YC6H2CH=NCH(CH2C6H4OH-4)COO] (R, X, Y = Et, H, H (1); n-Bu, H, Br (2); n-Bu, Br, Br (3)), have been synthesized by the one-pot reaction of diorganotin oxide, (L)-tyrosine and salicylaldehyde, and characterized by elemental analysis, IR, NMR, and X... see more
