Heterocyclic tautomerism. V. 2‐Guanidinobenzimidazole

Peter J. Steel

Open publisher page 19 citations

Abstract

Abstract A single‐crystal X‐ray structure analysis of 2‐guanidinobenzimidazole shows the molecule exists in the solid state as tautomer 1, with an intramolecular hydrogen bond between the benzimidazole‐N3 and a guanidino‐NH2. The guanidino group is inclined at an angle of 13.8° to the benzimidazole plane. Other nitrogen atoms and their attached hydrogens are involved in additional intermolecular hydrogen bonds that connect the molecules in a complex three‐dimensional network.
