Structural asymmetry, physicochemical characterization and optical properties of a new luminescent zero dimensional organic-inorganic hybrid compound

A novel 0D organic–inorganic hybrid antimony-based halide [((R)-C₈H₁₂N)₄](Sb₂Cl₁₀) was achieved through a slow evaporation method at room temperature. Single crystal X-ray diffraction analysis revealed that the compound crystallizes in the monoclinic system, within the P2₁ space group. The structure consists of(R)-1-phenylethylammonium (C₈H₁₂N)⁺cations and [Sb₂Cl₁₀]⁴⁻ dimers, formed by edge-sharing distorted octahedra. The cohesion of the structure were ensured by N-H…Cl hydrogen bonds. Hirshfeld surface analysis indicated H…H interactions as the dominant intermolecular interaction contacts (42.4 %). Infrared and Raman spectroscopy confirmed the presence of organic cations and inorganic components. The thermogravimetric analysis demonstrated that the compound exhibits thermal stability up to 180 °C. Finally, Optical studies further suggest that this material holds significant promise for optical and optoelectronic applications.
