Abstract: Complexes of the composition [M (L)2 (H2O)2].xH2O where L is deprotonated ligands like HL1 = 8-(-2-azothiazolyl-)-7- hydroxy 4-methyl coumarin and HL2 = 8-(-2-azobenzothiazolyl -)-7-hydroxy 4-methyl coumarin ; M = Mn(II), Co(II), Ni(II ), Cu(II) and Zn(II ); x = 1 to 4 have been synthesized and characterized by elemental analysis, magnetic susceptibility, molar conductance, TGA, X-ray diffraction and spectral studies. HL1 and HL2 act as neutral bidenate ligands and the complexes appear to be octahedral. Antibacterial activities of ligands and their metal complexes have been determined against Escherichia coli, Bacillus substilis, Klebsiella pheumoniae, Pseudomonas aerogens, Salmonalla paratyphi B, Staphylococcus  aureus and Proteus vulgaris.
