The preparation and characterization of a novel mixed metal complex of europium (III) and terbium (III) of a tripodal heptadentate Schiff-base ligand N [CH2CH2N=CH (2-OH-3-MeC6H3)]3 (H3L1) have been studied. The complex was prepared by the reaction of [EuL1] and [TbL1] in N, N-dimethylformamide. The ratio of europium (III) to terbium (III) in the mixed metal complex was found to be 3 to 7. The molecular structure of [Eu0.3Tb0.7L1] was determined by X-ray crystallography. The crystal structure analysis revealed that the Schiff-base behaves as a tri-deprotonated heptadentate ligand encapsulating the each metal ion within the N4O3 cavity. Under the excitation of UV light, the solid state of the complex exhibited red emission corresponding to europium (III) ion. The emission bands of 5D0 → 7Fj (j = 2, 3, 4) were observed at 609, 652, and 706 nm, respectively. On the other hand, the green emission corresponding to terbium (III) ion was not observed.

Schiff base ligand derived from glycine and benzaldehyde was synthesized together with its metal complexes (zinc and cobalt). The solubility, IR analysis and conductivity measurement were carried out. Antibacterial activities were evaluated using well-diffusion method. The bacterial assay was carried out on two pyogenic bacteria E. coli and Staphylococci and the results showed that the complexes have high antibacterial activity.

The present paper deals with the synthesis and characterization of metal complex of tridentate Schiff base ligand derived from the inserted condensation of 2-aminobenzimidazole (1H-benzimidazol-2-amine) with salicylaldehyde (2-hydroxybenzaldehyde) in a 1 : 1 molar ratio. Using this tridentate ligand, complex of Zn(II) with general formula ML has been synthesized. The synthesized complex was characterized by several techniques using molar conductance, elemental analysis, FT-IR, and mass and 1HNMR spectroscopy. The elemental analysis data suggest the stoichiometry to be 1 : 1 [M : L]. The complex is nonelectrolytic in nature as suggested by molar conductance measurements. Infrared spectral data indicate the coordination between the ligand and the central metal ion through deprotonated phenolic oxygen, imidazole nitrogen of benzimidazole ring, and azomethine nitrogen atom. Spectral studies suggest tetrahedral geometry for the complex. The pure compound, synthesized ligand, and metal complex were screened for their antimicrobial activity.

A novel ligand was synthesized from terephthalaldehyde and o-phenylene diamine and treated with coumarin derivative to form a New Schiff base. Co(II), Ni(II) and Cu(II) complexes of the ligand were synthesized. 1HNMR and LC-MS mass spectrometry studies were done. Antimicrobial studies were performed for the ligand and its metal complex with E.Coli and was found to be active. The ligand can be further modified and studied for its antimicrobial action in the future.
