Synthesis, complexation, spectral and antibacterial activity of 2-[Z-(hydroxyimino)methyl] phenol and its mn(II) complex

A new Schiff base, 2-[Z-(hydroxyimino)methyl]phenol (SAOX), has been synthesized from salicylaldehyde and hydroxylamine hydrochloride. 2-[E-(hydroxyimino)methyl] phenolmanganate(II) [Mn(SAOX)₂] was prepared from sulphate salt of Mn(II) in an alcoholic medium. The chemical structures of the SAOX and [Mn(SAOX)₂] were confirmed by various spectroscopic studies like IR, ¹H NMR, ESR, ESI-mass spectra, elemental analysis, molar conductance. On the basis of elemental and spectral studies, six coordinated geometry was assigned to these complexes. The free Schiff base and its complexes have been tested for their antibacterial activity by using disc diffusion method and the results discussed.
