New complexes of Ni(II) and Co(III) with a Schiff-base ligand derived from o -vanillin. Crystal structure, magnetic and catalytic properties of a dissymmetric binuclear nickel(II) complex

Polyhedron, 2018
A binuclear complex, [Ni2L2(NO3)(H2O)(CH3CN)]ClO4·CH3CN (1), has been obtained using a Schiff-base ligand (HL) derived from o-vanillin and 4-(2-aminoethyl)morpholine. The crystal structure of 1 has been solved.

Calorimetric determination of the standard molar enthalpies of formation of o-vanillin and trimethoprim

Journal of Thermal Analysis and Calorimetry, 2014
o-Vanillin and trimethoprim are two main raw materials for the synthesis of Valen Schiff bases which have been proved to possess established biological activities and may be used as the antibacterial agent candidates. The standard molar enthalpy of combustion and the standard molar enthalpy of formation of a substance are some of the most fundamental ...

Spectroscopic and theoretical study of the o-vanillin hydrazone of the mycobactericidal drug isoniazid

Journal of Molecular Structure, 2012
Abstract A complete and detailed study of the hydrazone obtained from condensation of antituberculous isoniazid (hydrazide of the isonicotinic acid, INH) and o -vanillin (2-hydroxy-3-methoxybenzaldehyde, o -HVa) is performed. It includes structural and spectroscopic analyses, comparing experimental and theoretical results. The compound was obtained
