Abstract
The new organic–inorganic hybrid material (C6H7N2S)2[SbCl4]Cl was synthesized by slow evaporation method and characterized by single-crystal X-ray diffraction, infrared absorption, Hirshfeld surface analysis, optical absorption and photoluminescence measurements. The Centro symmetric compound crystallizes in the triclinic system of space group $${\text{P}}\bar{1}$$P1¯ with two formula units cell (Z = 2).The crystal structure is composed of a discrete [SbCl4]− anion and two isolated chloride Cl− anions which carried the same negative charge to balance the total charge of this compound surrounded by the 4 pyridiniumethioamide cations. Organic and inorganic parts which are linked by means of hydrogen bonding contacts N–H···Cl with N···Cl length are varied in the range of 3.221–3.456 Å to form a Zero-dimensional network. The infrared study performed at room temperature charge in the 4000–400 cm−1 frequency regions confirms the existence of the organic cation [C6H7N2S]+ and that of the [SbCl4]− anion. The Photoluminescence spectrum exhibits a broad and strong band of luminescence located at 1.95 eV (635 nm), which can be even observed with the naked eye at room temperature and is due to exaction emission. The various intermolecular interactions of the two independent cations and six chloride atoms were examined via Hirshfeld surface analysis.
