Abstract

The in situ formed hydrazone Schiff base ligand (E)-N´-(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.
