N′-Hydroxypyridine-2-carboximidamide
Abstract
The title molecule, C6H7N3O, 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—H...N hydrogen bonds, forming inversion dimers with R22(10) motifs. The dimers are further linked into C(3) chains through O—H...N hydrogen bonds.
