Synthesis, crystal structure and characterization of a new Organic–inorganic hybrid material 4-(ammonium methyl) pipyridinium hexachloro stanate (II) trihydrate
The present paper undertakes the study of (C6H16N2) SnCl6.3H2O which is a new hybrid compound. It was prepared and characterized by single crystal X-ray diffraction, X-ray powder, Hirshfeld surface, Spectroscopy measurement, thermal study and photoluminescence properties. The single crystal X-ray diffraction studies revealed that the compound crystallizes in monoclinic Cc space group with cell parameters a= 8.3309(9) Å, b= 22.956(2) Å, c=9.8381(9) Å, β= 101.334(9) ° and Z=4. The atomic arrangement shows an alternation of organic and inorganic entities. The cohesion between these entities is performed via N–H···Cl, N-H···O, O–H···Cl and O-H···O hydrogen bonding to form a three-dimensional network. Hirshfeld surface analysis was used to investigate intermolecular interactions, as well 2D finger plots were conducted to reveal the contribution of these interactions in the crystal structure quantitatively. The X-ray powder is in agreement with the X-ray structure. Scanning electronic microscopy (SEM) was carried out. Furthermore, the room temperature infrared (IR) spectrum of the title compound was recorded and analyzed on the basis of data found in the literature. Solid state 13C NMR spectrum shows four signals, confirming the solid state structure determined by X-ray diffraction. Besides, the thermal analysis studies were performed, but no phase transition was found in the temperature range between 30 and 450 °C. The optical and PL properties of the compound were investigated in the solid state at room temperature and exhibited three bands at 348 and 401 cm-1 and a strong fluorescence at 480 nm.
