Structure-induced luminescence and bioactivities of Zinc(II) complexes with 2-(2,4-dichlorophenoxy)-N?-[pyridin-2-ylmethylene]acetohydrazide

The structure and photophysical properties of the series of Zn(II) complex with the hydrazone ligand, 2-(2,4dichlorophenoxy)-N '-[1-pyridin-2-ylmethylene]acetohydrazide, and different counter anions have been synthesized and characterized by single crystal X-ray diffraction, FT-IR, elemental analyses and ESI-MS. X-ray crystallography has proved the neutral or monoanionic form of ligand upon coordination. All complexes are mononuclear with the tetra/penta/hexacoordinated zinc atoms. The diverse supramolecular architectures of the complexes show that counter-anions have significant impacts on the structures. Furthermore DFT, luminescence properties, antibacterial and herbicide activities of the complexes have been investigated were carried out as well.

Automated summary

This article synthesized and characterized a series of Zn(II) complexes with a hydrazone ligand through single crystal X-ray diffraction, FT-IR, elemental analyses, and ESI-MS. X-ray crystallography confirmed the neutral or monoanionic form of the ligand upon coordination. The complexes were found to be mononuclear with tetra/penta/hexacoordinated zinc atoms. The supramolecular architectures of the complexes were significantly influenced by the counter anions. In addition, the complexes were investigated for their DFT, luminescence properties, antibacterial, and herbicide activities.
