J. Environ. Nanotechnol., Volume 3, No 2 (2014) pp. 188-193
Abstract
A new Mannich base, N-(1-Morpholinosalicylyl)benzohydrazide (MSB), formed by the condensation of morpholine, benzohydrazide and salicylaldehyde and its Co(II), Ni(II) Cu(II) and Zn(II) complexes have been synthesised. Their structures have been elucidated on the basis of analytical, magnetic, electrical conductivity and spectral methods. On the basis of colour,magnetic moments and spectral data, the geometries of Co(II), Ni(II), Cu(II) and Zn(II) complexes have been assigned. The electrochemical property of the ligand and its complexes in acetonitrile solution was studied by cyclic voltammetry. The X-band ESR spectra of the Cu(II) complex in DMSO at 300 and 77 K were recorded and their salient features are reported. Antibacterial activities of the ligand and its complexes were tested against some selected bacteria. The ligand and all the complexes showed antimicrobial activities.
