Abstract

Abstract : In the title compound, di‐μ‐acetato‐κ 2 O : O ;κ 2 O : O ′‐bis[(6‐chloro‐2‐{( E )‐[(pyridin‐2‐yl)methylimino]methyl}phenolato‐κ 3 N, N ′, O )zinc(II)], [Zn2 (C13 H10 ClN2 O)2 (C2 H3 O2 )2 ]·CHCl3, the Zn II cation adopts a five‐coordinate geometry and is coordinated by two N atoms and one O atom of a tridentate 6‐chloro‐2‐{( E )‐[(pyridin‐2‐yl)methylimino]methyl}phenolate ligand and two O atoms of two bridging acetate groups, but their coordination geometries differ. One Zn II cation adopts a distorted trigonal bipyramidal geometry and the other a square‐pyramidal geometry. The two acetate ligands bridge two Zn II cations with mono‐ and bidentate coordination modes. The title compound exhibits a strong emission at 460 nm upon excitation at 325 nm with a quantum yield of 23.1%.
