Zinc(II) complexes with nitrogen– and oxygen-containing hetero cyclic ligands attract considerable interest because of their structural diversity, bio logical relevance, and possible applications in medicine and materials science [1]. The introduction of fluorine-containing substituents, especially trifluoromethyl groups, can significantly affect the electronic properties, lipophilicity, and stability of the resulting coordination compounds [2]. Oxadiazine-type ligands formed through the cyclization of benzohydrazide derivatives are promising polydentate chelating agents for transition metal ions. The aim of this work was to synthesize and study a new zinc(II) chelate complex containing a 2,6-diphenyl-4-(trifluoromethyl)-1,3,5 oxadiazine fragment.
