Abstract:
Equimolar amounts of Himdazole-2-carboaldehyde and thiosemicarbazide were combined together
and Himdazole-2-carboaldehyde thiosemicarbazone was prepared. The synthesized lingad was
reacted with Cd (II), Hg (II) and Zn (II) ions yielding stable color complexes. For quantification
and characterization purpose, elemental analysis, molar conductivity, infrared spectra, electronic
spectra, proton nuclear magnetic resonance spectra, and mass spectra were carried out. The
magnetic moment was also used for characterization. The ligand of IR spectrum showed that
thiosemicarbazone coordinates to the metal ions via sulfur and azomethine nitrogen atom. The
measurements of magnetic moment for all complexes were found to be (0.00). In range of normal
for octahedral geometry and indicated all complexes were diamagnetic. An in vitro antimicrobial
have been tested against a number of bacteria and fungal strains for the free ligand and its metal
complexes, to assess their antimicrobial properties by diffusion technique. The ligand and its
complexes exhibit higher activity against bacteria and fungi in compared with standar
