Tetrazolate bridged dinuclear photo-luminescent zinc(II) Schiff base complex prepared via 1,3-dipolar cycloaddition at ambient condition

Abstract

A bis(μ-NN′-tetrazolate)-bridged centrosymmetric dinuclear zinc(II) Schiff base complex, [Zn₂(L)₂(PZTZ)₂] (HL is a tridentate Schiff base, 2-(2-(dimethylamino)ethyliminomethyl)-6-ethoxyphenol and HPZTZ is 2-pyrazinyltetrazole), has been synthesized via [3 + 2] cycloaddition of 2-cyanopyrazine and sodium azide in the presence of zinc(II) acetate dihydrate and HL. The structure of the complex is confirmed by single-crystal X-ray diffraction analysis. The complex shows fluorescence.
