Crystal Structure and Hirshfeld Surface Analysis of 2,2′-{(1E,1′E)-[Ethane-1,2-diylbis(Azanylyl-Idene)]bis-(Methanylyl-Idene)}bis-[4-(Trifluoro-Methoxy)phenol]copper(II) Hydro-Quinone Hemisolvate

Abstract

In the title complex, [Cu(C<inf>18</inf>H<inf>12</inf>F<inf>6</inf>N<inf>2</inf>O<inf>4</inf>)]·0.5C<inf>6</inf>H<inf>6</inf>O<inf>2</inf>, 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. © 2019 International Union of Crystallography.
