Ionic organic-inorganic (C6H10N2) (Hg2Cl5)2·3H2O compound Structural study, hirshfeld surface, thermal behavior and spectroscopic studies

International audienceA novel organic-inorganic hybrid material (C6H10N2)(Hg2Cl5)2·3H2O has been prepared under hydrothermal conditions. It is characterized by single crystal X-ray diffraction, thermal analysis and spectroscopy measurements (IR, Raman and NMR). The structural analysis revealed that this material crystallizes in the monoclinic system (C 2/c space group) with the following unit cell parameters a = 19.6830(15) Å b = 18.1870(15) Å c = 6.8567(6) Å β = 93.224(3) ° and Z = 4. According to the data collected at 150(2) K, the refinement converged to R = 0.0296. The atomic arrangement can be described as an alternation of cationic [C6H10N2]2+.H2O and anionic [Hg2Cl5]- layers along the c axis. In fact, a three-dimensional cohesion, which leads to these peridinium complexes, involves (N–H***Cl) (N–H***O) (O–H***O) and π–π interactions. Furthermore the FT-IR, Raman and NMR-MAS confirm the presence of organic and inorganic entities. Finally, the differential scanning calorimetry revealed several endothermic peaks
