Crystal structure and Hirshfeld surface analysis of 2,2′{(1 E,1′E)-[ethane-1,2-diyibis(azanylyunene)]-bis(methanylylidene)}bis[4-(traluorometnoxy)-phenol]copper(II) hydroquinone hermsoiyate

In the title complex, [Cu(C18H12F6N2O4)]center dot 0.5C(6)H(6)O(2), the Cu-II 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-diyl-bis (azanylylidene)] bis (methanylylidene)}bis [2-(trifluoromethoxy) phenol].The crystal packing is stabilized by intramolecular O-H center dot center dot center dot O and intermolecular C-H center dot center dot center dot F, C-H center dot center dot center dot O and C-H center dot center dot center dot pi hydrogen bonds. In addition, weak pi-pi 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 center dot center dot center dot H/H center dot center dot center dot F (25.7%), H center dot center dot center dot H (23.5%) and C center dot center dot center dot H/H center dot center dot center dot C (12.6%) interactions.
