Structural and Biological Studies on Some Coper(II) Macrocyclic Complexes

Abstract

Two new macrocyclic complexes were synthesized having the
formulae Cu[DPAODAH](BF₄)₂ and Cu[DPATDPH](BF₄)₂ {where
[DPAODAH] = diphenyl diacetic acid-N-oxy diacetic acid
dihydrazone and [DPATDPH] = diphenyl diacetic acid-N-thiodipropionic
acid dihydrazone and BF₄₂ = Tetrafluoroborate. The
complexes were characterized using molar conductance, magnetic
studies and infrared and electronic spectral data and have been
assigned octahedral geometries. The complexes were screened for
their biological studies against bacteria S. aureus and E. coli and
fungi A.flavus and C. albicans. The complexes were found to have
intense antimicrobial activity as contrasted with ligand fragments.
