Phenoxy-bridged binuclear Zn(II) complex holding salen ligand: Synthesis and structural characterization

•Synthesis of binuclear Zinc complex.•Presence of phenoxo-bridge.•One zinc ion exists in pentagonal pyramidal environment, while the another one occupies square planar geometry.

A novel binuclear phenoxo-bridged zinc complex obtained from the interaction of ligand, 2,2-(1E,1E)-(2,2-dimethylpropane-1,3-diyl)bis(azanylylidene) bis(methanylylidene)diphenol with zinc chloride is reported. The synthesized and isolated zinc complex has been characterized by FT-IR, 1H- and 13C- NMR, ESI-MS, TGA/DTA and single crystal X-ray diffraction studies. The phenoxo-bridge in this binuclear Zn(II) complex is due to the phenolic oxygen of the salen liagnd. The complex crystallizes in monoclinic P-1 space group, and different geometry has been assigned for both zinc ions in the complex.

Graphical abstractWe report the synthesis of a novel binuclear phenoxy-bridged zinc complex. The X-ray diffraction measurement shows that both the Zn(II) ions in the complex exists in different geometry.Figure optionsDownload full-size imageDownload as PowerPoint slide
