2-(1,3-Benzoxazol-2-yl)guanidinium chloride

Abstract

The non-H atoms of the cation of the title salt, C8H 9N4O+·Cl-, are approximately co-planar (r.m.s. deviation = 0.024 Å) with one amino group forming an intra-molecular hydrogen bond to the tertiary N atom of the benzoxazole fused-ring system. The cations and anions are linked by cyclic R21(6) N - H⋯Cl hydrogen-bonding associations, generating linear chains running along the a-axis direction. © Mohamed et al. 2011.
