Abstract
A new copper compound with general formula [H2L]2(CuCl4(H2O)2).2Cl·2H2O [L = 3,3′-diaminodiphenylsulfone] was synthesized, at room temperature, by slow evaporation method. The morphology was observed by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscope (EDS). The single crystal X-ray analysis indicates that the studied compound crystallizes in the P-1 triclinic space group. The packing pattern is characterized by organic and inorganic layers alternation stabilized by means of hydrogen interactions. Hirshfeld Surface analysis in combination with 2D fingerprint plots reveal the quantitatively relative contributions of these intermolecular interactions. Infrared and Raman spectroscopic analysis were performed to distinguish the different chemical functional groups and their environments in this compound. Additionally, the optical study was inspected by UV–visible and photoluminescence measurements. The compound exhibits three optical absorption bands at 245, 308 and 554 nm, with 1.54 and 1.64 eV indirect and direct gap energies values, respectively. Thermal analysis (TGA and DSC) was also investigated.
