Synthesis and crystallographic studies of two new 1,3,5-triazines.

摘要: The synthesis and characterization of two new 1,3,5-tri­azines containing 2-(amino­meth­yl)-1H-benzimidazole hydro­chloride as a substituent are reported, namely, 2-{[(4,6-di­chloro-1,3,5-triazin-2-yl)amino]­meth­yl}-1H-benzimidazol-3-ium chloride, C11H9Cl2N6+·Cl− (1), bis­(2,2′-{[(6-chloro-1,3,5-tri­azine-2,4-di­yl)bis­(aza­nedi­yl)]bis­(methyl­ene)}bis­(1H-benzimidazol-3-ium)) tetra­chloride hepta­hydrate, 2C19H18ClN92+·4Cl−·7H2O (2). Both salts were characterized using single-crystal X-ray diffraction analysis IR spectroscopy. Moreover, the NMR (1H 13C) spectra 1 obtained. Salts 2 have triclinic symmetry (space group P\overline{1}) their supra­molecular structures stabilized by hydrogen bonding offset π–π inter­actions. In hydrated salt 2, non­covalent inter­actions yield pseudo-nanotubes filled with chloride anions water mol­ecules, which modelled in refinement substitutional positional disorder.
