N′-Hydroxypyridine-2-carboximidamide

Abstract

Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.002 Å; R factor = 0.031; wR factor = 0.081; data-to-parameter ratio = 10.5.The title molecule, C 6 H 7 N 3 O, is almost planar (r.m.s. deviation = 0.0068 Å ) and adopts an E conformation about the C N double bond. In the crystal, molecules are linked by pairs of strong N-HÁ Á ÁN hydrogen bonds, forming inversion dimers with R 2 2 (10) motifs. The dimers are further linked into C(3) chains through O-HÁ Á ÁN hydrogen bonds. Related literature
