Synthesis, crystal structure and electrochemical studies of a hydrazone schiff base complex of titanium(IV)

Abstract

The in situ formed hydrazone Schiff base ligand (E)-Nt-(2- hydroxy-3-methoxybenzylidene)-benzohydrazide (L2-) reacts with bis(acetylacetonato)titanium(IV) oxide in methanol to a mononuclear [Ti(L)(OCH3)(acac)] complex which crystallizes in the monoclinic space group P21/c. a = 18.2786(13), b = 8.2609(5), c = 13.9008(10) Å, β = 96.809(3)° with Z = 4. Cyclic voltammetric experiments of the species in acetonitrile solution reveals a reversible peak at E° = -0.768 V (vs. Ag/AgCl) relating to the TiIV/TiIII redox process. © 2009 Verlag der Zeitschrift für Naturforschung.
