Abstract:
A new
series of transition metal complexes of Zn(II), Cd(II) and Hg(II)
with dibasic tridentate Schiff’s bases derived from
3-(4-chlorophenoxymethyl)-4-amino-5-mercapto-1,2,4-triazole with
substituted salicylaldehyde of the type ML(H2O)2
[where L is doubly deprotonated ligand and M= Zn(II), Cd(II) and
Hg(II)] have been synthesized and characterized by elemental
analysis, IR and NMR studies. All the complexes are colored and
amorphous in nature. The low values of conductance indicate
non-electrolytic nature for these complexes. On the basis of
spectral data a four coordinated tetrahedral geometry have been
proposed for these complexes. The ligands and its metal
complexes have been screened for their antibacterial activity
against E. coli and S. aurious and antifungal activity against
A. niger and A. flavous by Cup-plate method.
Keywords: Triazoles, Metal complexes, Spectral studies and
Antimicrobial activity.
