Cd(II) complexes of 2-substituted benzothiazole derivatives have been synthesized. The structural features have been determined from their microanalytical, magnetic susceptibility, IR, 1H NMR spectral data. All the Cd(II) complexes exhibit the composition [Cd(L-L)(A-A)] where L-L HPBT, MPBT and A-A, Leucine, Isoleucine, Valine. The N, O, S donor ligands and Amino acids act as a bidentate ligands in all the complexes. Tetrahedral geometry for all the Cd(II) complexes is proposed. The monomeric nature of the complexes was confirmed from their magnetic susceptibility values. All these complexes are coloured, thermally stable and non-electrolytic in nature. These complexes have been screened for their few fungal strains Aspergillus niger and Fusarium oxysporium.
