Crystal structure and Hirshfeld surface analysis of 2,2'-{(1,1')-[ethane-1,2-diylbis(aza-nylyl-idene)]bis-(methanylyl-idene)}bis-[4-(tri-fluoro-meth-oxy)phenol]copper(II) hydro-quinone hemisolvate.

In the title com-plex, [Cu(CHFNO)]·0.5CHO, the Cu ion has a square-planar coordination geometry, being ligated by two N and two O atoms of the tetra-dentate open-chain Schiff base ligand 6,6'-{(1,1')-[ethane-1,2-diylbis(aza-nylyl-idene)]bis-(methanylyl-idene)}bis-[2-(tri-fluoro-meth-oxy)phenol]. The crystal packing is stabilized by intra-molecular O-H⋯O and inter-molecular C-H⋯F, C-H⋯O and C-H⋯π hydrogen bonds. In addition, weak π-π inter-actions form a three-dimensional structure. Hirshfeld surface analysis and two-dimensional fingerprint plots were performed and created to analyze the inter-molecular inter-actions present in the crystal, indicating that the most important contributions for the crystal packing are from F⋯H/H⋯F (25.7%), H⋯H (23.5%) and C⋯H/H⋯C (12.6%) inter-actions.
