الملخص EN

In this work, a new orthorhombic organic-inorganic hybrid single crystal (C2H10N2)2MnBr4.2Br with-Zero-dimensional structure was synthesized by slow evaporation method at 75 °C.

The crystal structure and intermolecular interactions were performed by single crystal X-ray diffraction and Hirshfeld surface.

Optical properties of (C2H10N2)2MnBr4.2Br were systematically studied by Raman, infrared spectrum, UV–vis, photoexcitation spectra, and photoluminescence spectra.

The optical band gap (Eg = 2.61 eV) were calculated from the absorption spectra of (C2H10N2)2MnBr4.2Br.

This hybrid materials also had shown good thermal stability (decomposition temperature: 288–660 °C).

Finally, photoluminescence measurements showed a strong excitation line at 362 nm and a strong fluorescence at 537 nm which makes it a promising material in luminescence field.
