“…The pyridine rings in (I) are slightly distorted from planarity. A comparison with the theoretical geometric parameters for the nonprotonated amine, reported in the literature (Bryndal et al, 2012), indicates that the largest deviation from an aromatic ring plane occurs for atom C5 [0.056 (6) and 0.045 (5) Å for two independent molecules]. The geometries of the two cations are similar to each other.…”

Hybrid materials, fabricated by the combination of inorganic and organic components, have potential applications in chemistry and are endowed with the advantages of both building elements. There are several types of intermolecular interactions present in these hybrid compounds, including electrostatic forces, π-π stacking and hydrogen-bonding interactions, the latter playing an important role in the construction of three-dimensional architectures and stabilizing supramolecular crystal structures. Analysis of the intermolecular interactions and their influence on packing modes therefore requires focused scientific attention. Four new organic-inorganic salts, namely 2-amino-4-methyl-3-nitropyridinium hydrogen sulfate, CHNO·HSO, bis(2-amino-4-methyl-3-nitropyridinium) sulfate, 2CHNO·SO, 2-amino-3-methylpyridinium hydrogen sulfate, CHN·HSO, and bis(2-amino-3-methylpyridinium) sulfate monohydrate, 2CHN·SO·HO, have been synthesized and characterized by X-ray diffraction. The crystal structures are stabilized by intra- and intermolecular hydrogen bonds, as well as by weak π-π stacking and lp-π (lp is lone pair) interactions. Hirshfeld surface analysis was employed in order to study intermolecular interactions.

We report a series of high‐quality, low‐dimension, and bismuth‐based organic‐inorganic hybrid single crystals (C6H9N2)aBibXc (X=Cl, Br, I) fabricated via a simple hydrothermal method. The crystal structure, intermolecular interactions, morphology, chemical groups, bond characterization, and optical and thermal stability of the samples were detailed via X‐ray single crystal diffractomete, Hirshfeld surface analysis, field scanning electron microscopy (FSEM), fourier transform infrared spectrometer (FTIR), Raman, thermal gravimetric (TG), and Ultraviolet‐visible (UV‐vis) diffuse reflectance spectra. The results indicated that the (C6H9N2)2BiCl5 and (C6H9N2)2BiBr5 crystals displayed a monoclinic system with a P21/n space group at room temperature; the (C6H9N2)BiI4 crystal was P21/c. Meanwhile, the band gap could be continuously adjusted between 3.2 eV and 1.6 eV via the nature of halide ligands. The samples also have good thermal stability. The starting decomposition temperature of (C6H9N2)2BiCl5, (C6H9N2)2BiBr5, and (C6H9N2)BiI4 were 200 °C, 250 °C, and 300 °C, respectively. Therefore, this kind of organic‐inorganic hybrid compounds will be assumed to be a promising candidate for optical and electronic applications.
