Dioxomolybdenum (VI) Compounds of Macrocyclic Schiff base Ligands: Preparation, Characterization and Antibacterial Activity

Abstract

Using di-2-furanylethanedione and 5-bromo-3-methylbenzene-1,2-diamine we prepared a monomeric [MoO2(SL)] with a Schiff base, as well as 4 different compounds using the formulation [MoO2(MSL). We investigate how [MoO2(SL)] reacts with 1,3-diketones. Several characterizations are discussed in this article, including molar conductance measurement, elemental analysis, UV-Vis, IR, NMR, and thermal measurements. Molybdenum has a six-coordination number. All five MoO2(VI) compounds have distorted octahedral arrangements. Molybdenum octahedra have four N-atoms and two oxidized O-atoms. Against S. aureus and S. typhi, all synthesized compounds showed moderate activity. The chelation hypothesis is used to define the progression of the antibacterial task.
