Zinc carboxylates with nitrogen donor ligands have interest because of their potential biological applications [5]. Studies on the formation of mixed ligand complexes revealed their growing importance, in particular, their role in biological processes. The ternary complexes involving carboxylic acids as primary ligand and nitrogen containing molecules as secondary ligands can serve as useful models in metalloenzyme-catalyzed biochemical reactions [6]. Cinnamic acid and its hydroxyl derivatives are natural compounds that bind to hemicelluloses and celluloses in the cell wall of plants. They are also found naturally in products such as coffee beans, tobacco leaves and olive oil [7–9]. Cinnamic acid and related compounds attain special attention due to their ability to scavenge free radicals and protect the living species against certain carcinogens and mutagens [10–12].
