A new mannich base ligand formed by the condensation of tetrahydrocarbazole, phthalimide and p-dimethyaminobenzaldehyde and its complexation with transition metal ion Co(II), Ni(II) and Cu(II) are studied. The structures of the complexes have been elucidated on the basis of analytical chemistry, electrical conductivity and spectral study. The complexes were found to exhibit square planar geometry. The molar conductance for the metal complexes reveals the nature of the complexes as 1:2 electrolyte. The 1H NMR spectrum of the ligand was recorded in CDCl3 and the mass spectrum of the ligand reveals the molecular weight of the ligand to be m/z = 435.03. The EPR spectrum of the Cu(II) Complex was recorded at 77 K and its salient features are reported.

Mannich base, transition metal (II) complexes, spectral study, DNA cleavage, Anti oxidant study.
