Crystal structure and Hirshfeld surface analysis of 2,2′-{(1E,1′E)-[ethane-1,2-diylbis(aza­nylyl­idene)]-bis­(methanylyl­idene)}bis­[4-(tri­fluoro­meth­oxy)-phenol]copper(II) hydro­quinone hemisolvate.

In the title com­plex, [Cu(C18H12F6N2O4)]·0.5C6H6O2, the CuII ion has a square-planar coordination geometry, being ligated by two N and two O atoms of the tetra­dentate open-chain Schiff base ligand 6,6′-{(1E,1′E)-[ethane-1,2-diylbis(aza­nylyl­idene)]bis­(methanylyl­idene)}bis­[2-(tri­fluoro­meth­oxy)phenol]. The crystal packing is stabilized by intra­molecular O—H∙∙∙O and inter­molecular C—H∙∙∙F, C—H∙∙∙O and C—H∙∙∙π hydrogen bonds. In addition, weak π–π inter­actions form a three-dimensional structure. Hirshfeld surface analysis and two-dimensional fingerprint plots were performed and created to analyze the inter­molecular inter­actions 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%) inter­actions.
