The present work stems from our interest in the synthesis, characterization, and antibacterial evaluation of organosilicon(IV) complexes of a class of amino-acid-based Schiff base which have been prepared by the interaction of ethoxytrimethylsilane with the Schiff bases (N OH) in 1 : 1 molar ratio. These complexes have been characterized by elemental analysis, molar conductance, and spectroscop...

A tetranuclear mixed ligand copper(II) complex of a pyrazole containing Schiff base and a hydroxyhexahydropyrimidylpyrazole and copper(II) and nickel(II) complexes of the Schiff base having N-donor atoms have been investigated. A 2 equiv amount of 5-methyl-3-formylpyrazole (MPA) and 2 equiv of 1,3-diamino-2-propanol (1,3-DAP) on reaction with 1 equiv of copper(II) nitrate produce an unusual tet...

The synthesis of binuclear organometallic ruthenium complexes of an expanded porphyrin-type macrocycle is reported; pyrrolic hydrogen bonding donors were found to interact with ancillary ligands in the primary coordination sphere and to stabilize coordinated dioxygen in an eta(2)-fashion.

In this research, the interaction of [CuL(DMF)], [NiL(DMF)] and [VOL(DMF)] (where L = ((E)-4-((2-amino-5-nitrophenylimino)methyl)benzene-1,3-diol)) complexes derived from tridentate Schiff base ligand with bovine serum albumin (BSA) and DNA was investigated via electronic absorption and fluorescence spectroscopy. The Ultraviolet-Visible (UV-Vis) spectra exhibited an isosbestic point for the com...

118 Aprile ‘10 N onlinear optics (NLO) is the study of all the phenomena that occur from the interaction of intense light with matter [1, 2]. The interaction with a nonlinear optical material causes a modification of the optical properties of the system, and the next photon that arrives sees a different material. Typically only laser light is sufficiently intense to generate NLO phenomena; ther...

A new tetradentate Schiff base, 3-[(Z)-2-piperazin-1-yl-ethylimino]-1, 3-dihydro indol-2-one was synthesized by the condensation of isatin(Indole-2,3dione) with 1-(2-aminoethyl)piperazine(AEP). Its complexes with Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II), UO2(VI) and Th(IV) have been synthesized and characterized by microanalysis, conductivity, UV-visible, FT-IR, 1H NMR, TGA and magnetic s...
