Self Condensation Reaction of Thiosalicylic Acid in the Presence of Some Transition Metal Ions

Abstract

A new series of 16-membered tetrathiamacrocyclic complexes have been synthesized by the selfcondensation of thiosalicylic acid in the presence of transition metal ions and have been characterized by elemental analyses, IR, ¹H NMR, electronic spectral data, conductivity, and magnetic susceptibility measurements. An octahedral
geometry around the metal ion has been suggested for the nickel,
cobalt and zinc complexes, while a square-planar geometry is proposed
for the copper complexes.
