Synthesis and Biological activity of some complexes of (2-phenyl-4-arylidine imidazole-5-one) with some transition metal ions

A novel imidazole analogs of hipuric acids was synthesized by using acetic anhydride and acetic acid, then treated with hydrazine hydrate to give 3a-b. anew compounds were characterized by1HNMR,FTIR and UV spectroscopyand then were used as ligand and complication with some metals, these derivatives were investigated for their antimicrobial activity and antifungal. The prepared complexes were identified and their structural geometries were suggested by using elemental analysis (A.A), FT-IR and UV-Vis. spectroscopy, as well as magnetic susceptibility and conductivity measurements. Metal to ligand [M:L] ratio was obtained for all complexes in (ethanol) using molar ratio method, which gave comparable results with those obtained for the solid complexes.
