New divalent and trivalent transition metal complexes of 2-[(4 -[(Z)-1-(2-hydroxyphenyl)ethylidene]aminobutylethanimidoyl]phenol] were synthesized. The synthesized complexes were subjected to CHN, molar conductivity, magnetic moments, infrared, electronic and electron paramagnetic resonance spectra. The CHN elemental analyses showed the formation of 2:1 [M:L] ratio, The molar conductance measurements revealed the presence of non-electrolytic nature. infrared spectral results displayed the involvement of azomethine nitrogen atom and hydroxyl groups in coordination to the central metal ion. On the basis of electronic and electron paramagnetic resonance spectral studies, an octahedral structure was proposed for all complexes. Also the antibacterial activity of the Schiff base and its chelates were screened on some pathogenic bacteria.
