Abstract:
In the title compound, C(19)H(13)N(5)·C(4)H(8)O(2)·2H(2)O, the mol-ecular skeleton of the 2,6-bis-(benzimidazol-2-yl)pyridine (bbip) mol-ecule is essentially planar (r.m.s. deviation = 0.023 Å). An extensive three-dimensional network of inter-molecular N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds consolidates the crystal packing, which also exhibits π-π inter-actions between the five- and six-membered rings from neighbouring bbip mol-ecules.

Nomenclature of Carboxylic Acid Derivatives: Acid Halides, Esters, and Acid Anhydrides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
