2-(2-{[2-(2-Pyridylcarbon-yl)hydrazono]meth-yl}phen-oxy)acetic acid

摘要

In the title compound, C15H13N3O4, the pyridine and benzene rings are nearly coplanar [dihedral angle = 4.92?(12)°]. The maximum deviation from the best least-squares plane calculated for the main mol-ecular skeleton is 0.1722?(1)?? for the carbonyl O atom. In the crystal, inter-molecular O—H?O hydrogen bonds connect the mol-ecules into a chain, while π–π stacking inter-actions between the pyridine and benzene rings [centroid–centroid distance = 3.9162?(8)?? and offset angle = 27.20°] complete a two-dimensional network.
