Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <p>A new series of Cr(III) macrocyclic complexes have been synthesized by template condensation of ligands 2-[4-chloro-2-(2-oxo-1, 2-diphenyl-ethylideneamino)-phenylimino]-1, 2-diphenyl-ethanone (ML¹) and 2-[4-fluro-2-(2-oxo-1, 2-diphenyl-ethylideneamino)-phenylimino]-1, 2-diphenyl-ethanone (ML²) respectively, with appropriate diamines i.e. 1, 2-phenylenediamine, 4- chloro 1, 2-phenylenediamine and 4-fluro- 1, 2-phenylenediamine in the presence of CrCl₃.6H₂O. The ligands and their complexes have been characterized on the basis of elemental analyses, molecular weight determinations, conductance and magnetic susceptibility measurements and spectral studies including IR, ESR, electronic spectra and X-ray powder diffraction studies. On the basis of these studies, a six-coordinated octahedral geometry has been proposed for all these complexes. The newly synthesized ligands and their complexes have been screened for their antimicrobial, nematicidal and pesticidal activities. The results are indeed positive.</p> </abstract>
