Expanding on prior research with 8‐hydroxyquinoline (8hq) derivatives, this study investigates 5,7‐dibromo‐8‐hydroxyquinoline (8hqBr 2 ) as a ligand in organic–inorganic hybrid materials (OIHMs). A series of 19 compounds and two its salts were synthesized, employing d‐ p‐block metal halides to explore the effect solid‐state supramolecular structures emission properties. Through use density functional theory (DFT), work emphasizes critical role bromine position within ligand, contrasting when located exclusively halogenometallate anions. The findings reveal that is profoundly influenced by π–π stacking, anion‐π interactions, configuration cations substituents. This not only provides insights into specific impact positioning 8hqBr fluorescence but also contributes development advanced emitters for optoelectronics sensing, enhancing understanding modulation 8‐hydroxyquinoline‐based OIHMs.

This study details the synthesis and characterization of a series organic–inorganic hybrid materials (OIHMs) based on 5,7-dichloro-8-hydroxyquinolinium cations combined with open-shell [Fe(III), Cu(II)] as well close-shell [Zn(II), Cd(II), Hg(II), Sn(IV)] halogenometalate anions, showcasing diverse geometries complex intermolecular interactions. The revealed definite correlation between fluorescence characteristics associated structural electronic factors, among which presence water molecules instigated quenching. In case mercury-based compounds, notable enhancement in was linked to reduced quantity within crystal lattice, leading fewer water-mediated interactions consequently increased fluorescence. Surprisingly, bromides exceeded chlorides terms intensity, result credited anion-π halogen-water research highlights substantial role these play, offering invaluable insights into fluorescence-based technologies. Moreover, it underscores necessity for comprehensive understanding elements relation properties.
