Condensation of 2-hydroxy-1-naphthaldehyde with 2-amino-3-carboxyethyl-4,5-dimethylthiophene in 1:1 molar ratio, yielded a potentially tridentate Schiff base viz.
2-[N-(20-hydroxy-1- naphthylidene)amino]-3-carboxyethyl-4,5-dimethylthiophene (HNAT).
This ligand formed complexes with lanthanum(III), cerium(III), praseodymium(III), neodymium(III), samarium(III), europium(III) and gadolinium(III) chloride under well defined conditions.
These complexes were characterized through elemental analysis, molar conductance, magnetic moment measurements, IR, UV–Vis, FAB mass and 1H NMR spectral studies.
Analytical data showed that all the metal complexes exhibited 1:1 metal–ligand ratio.
Molar conductance values adequately confirmed the non-electrolytic nature of the metal complexes.
The proton NMR spectral observations supplement the IR spectral assignments.
The spectral data revealed that the ligand acted as neutral tridentate, coordinating to the metal ion through azomethine nitrogen, ester carbonyl and naphtholate oxygen without deprotonation.
The ligand and its lanthanum(III) chloride complex were subjected to XRD studies.
The lanthanum(III) chloride complex has undergone a facile transesterification reaction.
The solid state d.c.
electrical conductivity of some selected complexes were measured as a function of temperature, indicating the semiconducting nature of the metal complexes.
The antimicrobial activities were examined by disk diffusion method against some pathogenic bacterial and fungal species.
