SYNTHESIS AND CRYSTAL-STRUCTURE OF A BINUCLEAR ZINC(II) COMPLEX OF 2,6-DIFORMYLPYRIDINE N-OXIDE BIS(BENZOYLHYDRAZONE)

The binuclear zinc(II) complex [Zn(2)L(O2CCH3)(2)]. CH3CH2OH was synthesized by a template reaction in alcohol. The crystal and molecular structure of this complex has been determined by X-ray analysis. The binucleating ligand L, 2,6-diformylpyridine N-oxide bis(benzoylhydrazone), is in doubly deprotonated form. All the coordinated atoms in the bis-Schiff base ligand and two zinc atoms in the complex molecule are coplanar, and the N-oxide oxygen atom bridges two zinc atoms with the same bond length of 2.24(1) Angstrom. The two acetate ions act as bidentate ligands linking two zinc atoms, both being in a distorted trigonal-bipyramidal environment.
