Abstract
The asymmetric unit of the title salt comprises two 1,3-dihydro-2H-benzimidazol-2-iminium cations and two 2-hydroxy-5-sulfobenzoate anions (Z′ = 2). In the crystal, the molecules interact through N—H⋯O, O—H⋯O hydrogen bonds and C—O⋯π contacts. The hydrogen-bonding interactions lead to the formation of layers parallel to (
01).
The asymmetric unit of the title salt, C7H8N3+·C7H5O6S−, comprises two 1,3-dihydro-2H-benzimidazol-2-iminium cations and two 2-hydroxy-5-sulfobenzoate anions (Z′ = 2). In the crystal, the molecules interact through N—H⋯O, O—H⋯O hydrogen bonds and C—O⋯π contacts. The hydrogen-bonding interactions lead to the formation of layers parallel to (
01). Hirshfeld surface analysis revealed that H⋯H contacts contribute to most of the crystal packing with 38.9%, followed by H⋯O contacts with 36.2%.
期刊介绍:
Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
