Abstract

In this manuscript we report the synthesis and characterization of two new polynuclear zinc(ii) complexes, [Zn₂L¹(μ-OAc)₃]_n·H₂O (1) and [Zn₂L²(μ-OAc)₃]_n (2) using two tridentate ligands, HL¹ {4-chloro-2-(((2-(methylamino)ethyl)amino)methyl)phenol} and HL² {2,4-dibromo-6-(((3-(methylamino)propyl)amino)methyl)phenol}. The structures were confirmed by single-crystal X-ray diffraction analysis. Both complexes form 1D chains. The energy of H-bonding interaction in the solid state structures of the complexes has been estimated by DFT calculation and the crucial role of hydrogen bonding in shaping their structures has been highlighted.
