“…The procedure reported 3 for the preparation of [Cu(salacac)] was used with slight modification. In a typical procedure, a mixture of Cinac (0⋅01 M) and 3 drops of piperidine in chloroform (50 ml) was gradually added to a suspension of hydrated copper acetate (0⋅01 M) in chloroform (50 ml) and stirred in a round bottomed flask.…”

A bidentate ligand derived from cinnamaldehyde and acetylacetone and its copper(II) complex have been synthesized and characterized by elemental analysis, UV-Vis, IR, ESR and magnetic susceptibility measurements. Magnetic susceptibility measurements, ESR and electronic spectral data indicate the presence of six coordinated Cu(II) ion. The ligand and complex are tested for antibacterial activity against Pseudomonas aeroginosa. They are found to show the antibacterial activity.

“…Prospective metals are Co, Zn, Cu and Ni where the complex formation was observed with the neutral β-diketone ligands. 143 So far, the organic tethers explored in this research were not in π-conjugation with the indigoid core with exception of the oxalyl tether. A π-conjugated bridge moiety will be an interesting addition to the library of cis-indigos as it is anticipated that absorption wavelengths, redox potentials and acidity (for Nindigo) could be expanded.…”

A new series of nickel(II), cobalt(II)/(III) and copper(II) complexes of 14, 15 and 16-membered of macrocyclic ligands have been prepared and characterized by elemental analyses, IR, UV-VIS and 1 H-NMR spectra, magnetic susceptibilities, conductivities, DTA and ESR measurements. Molar conductances in DMF solution indicate that, the complexes are nonelectrolytes except (9-12) complexes. The electronic spectra show that, all complexes are square planar or distorted octahedral geometry. The ESR spectra of solid complexes (4), (8) and (11) show square planar of axial type symmetry (dx2-y2) with considerable covalent bond character. However, complex (12) shows a spectrum of octahedral geometry with dz2 ground state. Complex (12) shows exploitation in reducing the amount of electron adducts formed in DNA during irradiation with low radiation products.
