Synthesis, crystal structures, and urease inhibition of an acetohydroxamate-coordinated oxovanadium(V) complex derived from N′-(3-bromo-2-hydroxybenzylidene)-4-methoxybenzohydrazide

A novel chlorido-bridged dinuclear manganese(III) complex, [Mn 2 L 2 (μ-Cl)Cl 2 )]·Cl·0.5CH 3 OH, where L is the zwitterionic form of N,N'-bis(5-methylsalicylidene)diethylenetriamine, has been prepared and characterized by elemental analyses, IR, and single crystal X-ray crystallographic determination. The crystal of the complex is monoclinic: space group C2/c, a = 20.0300 (9), b = 22.8494(8), c = 22.127(1) Å, β = 112.882(3)°, V = 9330.0(7) Å 3 , Z = 8. The asymmetric unit of the compound contains two dinuclear manganese complex cations, two chloride anions, and one methanol solvate. The Schiff base ligand coordinates to two Mn atoms through the phenolate O and imine N atoms, with the amine N atom protonated. The effect of the complex on the antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans was studied.

Two new V V complexes with the bromo-substituted hydrazones N'-(3-bromo-2-hydroxybenzylidene)-3-hydroxy-4-methoxybenzohydrazide (H 2 L 1), N'-(3-bromo-2-hydroxybenzylidene)-3,5-dimethoxybenzohydrazide (H 2 L 2), [VOL 1 (OCH 3)(CH 3 OH)] (1) and [VOL 2 (OCH 3)(CH 3 OH)] (2), were synthesized and structurally characterized by IR, UV-Vis and 1 H NMR spectroscopy, as well as single-crystal X-ray determination. The V atom in the mononuclear complexes are six-coordinated in octahedral geometry. The free hydrazones and the complexes were studied on their antibacterial activity on S. aureus, B. subtilis, E. coli and P. fluorescence, and antifungal activity on C. albicans and A. niger. The bromo groups of the hydrazone ligands may increase their antibacterial activity.

“…[1][2][3][4][5][6] In recent years, metal complexes of Schiff bases have attracted considerable attention due to their remarkable biological activity, such as antifungal, antibacterial and antitumor property. [7][8][9] It has been shown that the Schiff base complexes derived from salicylaldehyde and its derivatives with primary amines, bearing the N 2 O, N 2 S, NO 2 or NSO donor sets, have interesting biological activity. [9][10][11][12] Furthermore, cobalt complexes in its varied oxidation states have become a central theme of current research because of their potentially useful properties in the realm of relevant scientific and technological fields.…”

Abstract). The complexes have been characterized by elemental analyses, IR spectroscopy, and single-crystal X-ray diffraction. The L 1 ligand coordinates to the Co atom through the phenolate O and carbonyl O atoms, while the L 2 ligand coordinates to the Co atom through the phenolate O and imino N atoms. The Co atom in complex 1 adopts octahedral coordination and that in complex 2 adopts tetrahedral coordination. The effect of the free ligands and the cobalt complexes on the antimicrobial activities against Staphylococcus aureus, Escherichia coli, and Candida albicans was studied.
