Abstract
Metalcomplexes of Schiff bases have occupied a central role in the dc\’Clopmenoft coordination chemistry.
The new p-diketone Schiff bases phenylhydrazone ligands (L), are prepared by the condensation of some substituted Knovenagel condensates ”’lib phenylhydrazone in absolute ethanol. The ligands have the general IlUCtural formula:

The aim of this study is to prepare, in very high purity grade, and dluacterize some new Schiff bases phenylhydrazones and their metal
