Abstract
AbstractReaction of 5-aminosalicylic acid with 2-pyridinecarboxaldehyde or sodium chloroacetate gave two new ligands 5-((pyridin-2-yl)methyleneamino)-2-hydroxybenzoic acid (HL1) and 5-(bis(carboxymethyl)amino)-2-hydroxybenzoic acid (H2L2), respectively. Two compounds [Co(L1)2(H2O)2]·2H2O (1) and [Cu2(L2)2(phen)2] (2) (phen = 1,10-phenanthroline) were synthesized and characterized by IR, PXRD, TGA and cyclic voltammetry. Single crystal X-ray diffraction analysis reveals that complex 1 is a mononuclear structure and the metal center is coordinated in an octahedral geometry. Complex 2 is a dinuclear structure, in which the Cu atom is in a square pyramidal geometry. Graphical AbstractThe cobalt ion is chelated by two 5-((pyridine-2-yl)methyleneamino)-2-hydroxybenzoinates to form a mononuclear structure. The compound an electrocatalytic activity of the reduction reaction from H2O2 to H2O.
