The present paper is a report on the synthesis of some Co(II), Ni(II) and Cu(II) complexes by the condensation of 2 ethyl indole 3-carboxaldehyde with thiosemicarbazide hydrochloride using ethanol as reaction medium. The bonding pattern and structural studies of ligand and complexes have been carried out on the basis of elemental analyses, molar mass, IR spectra, electronic spectra, molar conductance and magnetic susceptibility measurements. The nonelectrolytic nature of the complexes has been proposed on the basis of their molar mass determination and conductance measurements. The ligand and their complexes have been screened in vitro for their antimicrobial activity. Some of the reported complexes were found to be quite active.
