AI InsightThe crystal packing is stabilized by intramolecular N–H···O, N–H···Cl, the intermolecular N–H···Cl interactions link the molecules into a two-dimensional network and between anions and the water molecules. π-π contacts between benzimidazole rings [centroid–centroid distances = 3.4642 (2) Å, 3.5309 (2) Å and 3.5527 (2) Å] may further stabilize the structure.

Abstract
In this study, we synthesized a novel benzimidazole-based Schiff base; (E)-4,4'-methylenebis(2-((E)-(((1H-benzo[d]imidazol-2-yl)methyl)imino)methyl)phenol) ( 3 ) was synthesized by the condensation of 5,5'-methylenebis(2-hydroxybenzaldehyde) ( 1 ) and (1H-benzo[d]imidazol-2-yl)methanamine.HCl salt ( 2 ). This Schiff base derivative was reported for the first time and was fully characterized by FT-IR, UV–vis, 1 H-NMR, 13 C-NMR and mass spectroscopy. Electronic absorption and fluorescence titration studies of 3 with different metal cations in a DMF show a highly selective binding affinity only toward and Zn 2+ ion. The crystal structure of 2 , C 8 H 13 Cl 2 N 3 O, has been determined by single crystal X-ray diffraction method. The crystal structure of the title compound, C 8 H 11 N 3 2+ × 2(Cl — ) × H 2 O, consists of an organic 1H-benzoimidazol-3-ium (C 8 H 11 N 3 2+ ) cation, an inorganic 2(Cl — ) anion and one water (H 2 O) molecule. In the cation of the title compound, C 8 H 11 N 3 2+ , the benzimidazole ring system is planar with a maximum deviation of -0.012 (3) Å. The crystal belongs to monoclinic system, space group P 2 1 / c. The crystal packing is stabilized by intramolecular N–H···O, N–H···Cl, the intermolecular N–H···Cl interactions link the molecules into a two-dimensional network and between anions and the water molecules. π-π contacts between benzimidazole rings [centroid–centroid distances = 3.4642 (2) Å, 3.5309 (2) Å and 3.5527 (2) Å] may further stabilize the structure.
