Synthesis, intermolecular interactions and biological activities of two new organic–inorganic hybrids C(6)H(10)N(2),2Br and C(6)H(10)N(2),2Cl·H(2)O

A slow evaporation method has permitted the crystallization of two novel crystals of (2-aminomethyl)pyridindiumdihalide C(6)H(10)N(2),2Br (1) and C(6)H(10)N(2),2Cl·H(2)O (2). The structures of the prepared compounds (1) and (2) were elucidated by single-crystal X-ray diffraction which revealed that they crystallize, respectively, with triclinic and monoclinic symmetries. Their crystal packing was stabilized by non-covalent interactions, including N–H⋯Br, C–H⋯Br, N–H⋯Cl, O–H⋯Cl and N–H⋯O hydrogen bonds. 3-D Hirshfeld surface analysis followed by 2-D fingerprint schemes gives insights into the intermolecular interactions in the crystalline structure. Furthermore, the FT-IR spectroscopy of these two compounds was carried out. The synthesized products were also screened for in vitro antioxidant and antimicrobial activities, which reveals their favourable antioxidant activities against 1,1-diphenyl-2-picrylhydrazyl (DPPH) as well as the discolouration of β-carotene.
