摘要

Organic–inorganic hybrid materials based on metallic halides are increasingly attractive due to their non-toxicity and straightforward synthesis. In this work, a novel hybrid compound (C7H10N2)ZnI2⋅H2O was synthesized via slow evaporation at room temperature. Single-crystal X-ray diffraction confirmed a zero-dimensional structure with space group P2/c and unit cell parameters a = 16.9488(7) Å, b = 6.0285(2) Å, c = 13.6096(6) Å, β = 97.641(4)°, and V = 1378.22(10) Å3. Hirshfeld surface analysis was used to assess the diversity of intermolecular interactions involving the organic and inorganic entities. IR and Raman spectroscopy verified the hybrid nature of the material. Thermal analysis (TG/DTG and DSC studies) identified two anomalies at 315 and 369 K, further highlighting its unique properties. Optical studies revealed a direct band gap, with photoluminescence showing a broad blue emission, indicating semiconductor behavior and proving that the compound (C7H10N2)ZnI2⋅H2O could be useful in solar energy conversion devices and photovoltaic technologies. The hybrid perovskite material exhibits remarkable dielectric characteristics, boasting a high dielectric constant and minimal dielectric loss. These exceptional electrical properties open exciting avenues for technological innovation, with promise in the field of electronic capacitors.
