AbstractA novel hybrid compound, based on iron, fluoride and 8-hyroxyquinoline, and formulated as (8HQN)6[Fe4F18] (QF1), has been obtained by hydrothermal method and characterized by single crystal X-ray diffraction (SCXRD), powder X-ray diffraction (PXRD), Hirschfeld surface, IR spectroscopy, photoluminescence (PL), thermal analysis and magnetic study. (QF1) crystalizes in trigonal space group R3c with cell parameters a = 17.9239(5) Å, b = 17.9239(5) Å, c = 30.6196 (11) Å, V = 8519.1(5) Å3, and Z = 6. The crystal structure of (QF1) is built up from isolated tetramers [Fe4F18]6− surrounded by six cations 8HQN+. The cohesion between these entities is performed via NH⋯F and OH⋯F hydrogen bonds to form a three-dimensional network. Hirshfeld surface analysis was used to investigate intermolecular interactions, as well 2D finger plots were conducted to reveal the contribution of these interactions in the crystal structure quantitatively. IR spectra confirmed the presence of 8-hydroxyquinoleine molecules. The photoluminescence studies of (QF1) show a significate green emission at 2.14 eV associated with radiative recombination of excitons confined within the organic part when it was excited in UV–visible wavelength in the solid state at room temperature. Finally, the magnetic analysis shows that (QF1) has a paramagnetic behavior above 100 K.
