Abstract
A new 5-bromo-2-hydroxobenzaldehyde S-ethylisothiosemicarbazone hydroiodide free Schiff base (H2L) is synthesized and a series of molybdenum(VI) complexes, MoIVO2LD, have prepared where D can be DMF, DMSO and pyridine. The compounds are characterized with molar conductance, FT-IR, 1H NMR, elemental analyses, and UV-Vis techniques. Structures of complexes are determined with X-ray analysis. All experimental results confirmed that H2L is a tridentate bi-deprotonated ligand (ONN), coordinating through phenolic oxygen, azomethine nitrogen, and isothioamide nitrogen. The neutral complexes are distorted octahedral.
