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.
