L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Crystal structure of a new pentadentate symmetrical: di[4-(phenylimino)pentan-2-one] ether. Structural and electrochemical studies of its CoII, NiII, CuII and CdII complexes

“…Among them very few reported the behaviour of Schiff bases bearing an ether functional group [16,17]. In our continuous work about symmetrical Schiff bases, with various links between the symmetrical moieties [19,20], we describe here a new series of complexes with a new symmetrical potent pentadentate base as ligand: di [4-(phenylimino)pentan-2-one] ether in order to obtain some complex species useful to extract metal from environment. The crystal structure of the ligand is given; the structures of the complexes and their electrochemical properties are described.…”

Structural and electrochemical studies of Co(II), Ni(II), Cu(II) and Cd(II) complexes with a new symmetrical N2O2 Schiff base: Crystal structure of the ligand 1,2-di[4-(2-imino 4-oxo pentane)phenyl]ethane

“…In our continuous work about symmetric Schiff bases built around 4,4 0 -diaminodiphenyl [8,9] we present here the crystal structure of a new symmetrical compound: 1,2-di[4-(2-imino 4-oxo pentane)phenyl]ethane (see Fig. 1) obtained by reacting 4,4 0 -diaminodiphenyl with acetylacetone.…”

Synthesis, characterization, cyclic voltammetry and biological studies of Zn (II), Cd (II), Hg (II) and UO22+ complexes of thiosemicarbazone salt

“…The stability constant ( β MX ), formal peak potential and Gibbs free energy (Δ G ) for CdCl 2 complex were estimated using the following equation: where E ° M is the formal peak potential for the metal without the ligand, E ° C is the formal peak potential of metal chelate after each addition of NaH 3 PyTSC, R is a gas constant (8.314 J mol −1 degree −1 ), T is the absolute temperature, j is the coordination number of the complex, and C x is the concentration of ligand in the solution.…”
