• Synthesis of cadmium complexes of 4'-chloro-terpyridine: From discrete dimer to 1D chain polymer, crystal structure and antibacterial activity

Two new Cd(II) complexes with the ligand 4'-chloro-2,2':6',2"-terpyridine (Cltpy), [Cd(Cltpy)(N3)(CH3COO)], 1, and [Cd(Cltpy)(NCS)(CH3COO)]$_n$, 2, have been synthesized and characterized by CHN elemental analyses, 1HNMR-, 13C NMR-, IR spectroscopy and structurally analysed by X-ray singlecrystal diffraction. The single crystal X-ray analyses show that the coordination number in these complexes is seven with three terpyridine (Cltpy) N-donor atoms, two acetate oxygens and two anionic bridged ligands. The crystal structure of 2 comprises a one-dimensional polymeric network bridged by NCS anions. The antibacterial activities of Cltpy and its Cd(II) complexes are tested against different bacteria. Both complexes have shown good activity against all the tested bacteria. Against Klebsiella pneumonia and Staphylococcus aureus, antibacterial activity of complexes is higher than Cltpy ligand. The higher activity of complexes may be explained on the basis of chelation theory.

• Synthesis of dark brown single-walled carbon nanotubes and their characterization by HSQC-NMR

We report here a simple and effective approach to the covalent attachment of single-walled carbon nanotubes (SWCNTs) and azo compounds. The functionalized SWCNTs prepared (through a radical mechanism) have been used for a diazonium coupling reaction. The results showed that the chemical method used has improved the processability and solubility of the carbon nanotubes. The dark brown SWCNTs obtained which can produce a yellow colour in organic solvents were characterized by different spectroscopic analyses. Heteronuclear single quantum coherence spectra (13C-1H HSQC) have been used to detect the carbon nanotube allylic protons. The morphology of the main product has been shown by scanning electron microscopy (SEM).
