Seven coordinate lanthanide(III) complexes with N,N'-bis(2-hydroxyphenyl)- pyridine-2,6-dicarboxamide (BHPPDAH) with the general composition [Ln(BHPPDA)(H2O)2]NO3, where Ln = La(III), Pr(III), Nd(III), Sm(III), Eu(III), Gd(III), Tb(III), Dy(III) and Y(III), have been isolated. The complexes have been characterized based on magnetic susceptibility, conductivity studies, IR, NMR, UV-VIS, EPR and thermal studies. The ligand binds to themetal centre through pyridine and amide nitrogens and doubly deprotonated phenolic oxygens. Biological evaluation of the complexes indicates enhanced activity compared with that of free ligand.
