“…The past decade has included studies on their syntheses and characterization [10,11], preparation of their mono-nuclear [12][13][14], homo- [15] and hetero-polynuclear [16,17], and polymeric metal complexes [18][19][20]. Flourescence [21], optical [22][23][24], biological [25,26], electrochemical [27][28][29], and thermal properties [30,31] have been of particular interest. In addition, X-ray crystal structures [32,33], IR on Longmir-Blodget films [34,35], biodistribution [36] and extraction studies [37], determination of metal ions [38,39] and photoelectrical behaviors [40] have all been reported.…”

A new vicinal dioxime ligand containing azo and thione chromophores, namely 1,3-bis[4-(phenyldiazenyl)-phenyl]-2-thiooxaimidazoline-4,5-dione dioxime (bppH 2 ), was synthesized by the reaction of cyanogen di-N-oxide with N,N 0 -bis(4-phenylazophenyl) thiourea in dichloromethane solution at -10°C. Mononuclear complexes of bppH 2 with nickel(II), cobalt(II), and copper(II) were synthesized. The complexes, [Ni(bppH) 2 ], [Cu(bppH) 2 ], and [Co(bppH) 2 ] were characterized by several techniques using elemental analyses, conductivity measurements, FT-IR, and electronic spectral studies. The data suggest that the ligand coordinates through the N,N atoms, as do most vic-dioximes. The molar conductivities in DMF solution indicate nonelectrolytic nature for the complexes. Antimicrobial activities of the ligand and its metal complexes were estimated for five bacteria, namely Klebsiella pneumoniae, Micrococcus luteus, Mycobacterium smegmatis, Enterobacter cloaca and Bacillus megaterium and three fungi, namely Candida albicans, Kluyveromyces marxianus, and Rhodotorula rubra.

“…Table 1 also shows that the complexation strength in both methanol and water are approximately the same. Nevertheless, the resulting L-Cu 2þ complex in H 2 O is somewhat weaker than that in MeOH solution, due to the increased solvating ability and dielectric constant of water relative to methanol [14,21,22].…”

The complexation of a recently synthesized aminoxanthone derivative, 1-({2-[(2-aminoethyl) amino]ethyl}amino)-6-methyl-9H-xanthen-9-one with Cu(II) in methanol and water solutions, was investigated by spectrofluorimetric and spectrophotometric methods. The possible molecular geometries, bindings, and spectroscopic properties for the formed complex were theoretically studied in detail by the Hyperchem program. The stoichiometry of the complex was determined from spectrophotometric molar ratio methods at 20 C. The spectral data were further treated by KINFIT program to calculate the formation constant of the 1 : 3 complex and its molar absorptivity. Program DATAN was used to calculate the spectral behavior of the complex in each solution for different mole ratios. A simple equation for the determination of complex stability constant was also evaluated from titration data. Under the optimal conditions, the ligand can be used as a fluorometric indicator for measuring Cu 2þ ions in aqueous solution.
