Abstract
A novel series of nano-sized zinc(II) complexes of type [{Zn(M)(H2O)2}(CH3COO–)2] (where M =
macrocyclic ligands) has been synthesized by the in situ reactions of Schiff bases derived from
3-(phenyl/substituted phenyl)-4-amino-5-hydrazino-1,2,4-triazoles, salicyldehyde/2-hydroxy-1-
naphthaldehyde and 1,4-dibromobutane/1,5-dibromopentane in presence of zinc(II) acetate dihydrate
in absolute ethanol. The structures of all these zinc(II) complexes were established on the basis of
elemental analyses and spectral data (IR, 1H NMR and 13C NMR). Scanning electron microscopy
studies have been carried out to investigate the particle size and surface morphology of a particular
complex while thermal studies confirm the presence of coordinated water molecules in all the zinc(II)
complexes. The antimicrobial effects of all the synthesized complexes were studied against different
species of pathogenic fungi and bacteria.
