Abstract
A novel compound of 2-oxo-1,2-dihydropyridine-1-acetic acid was synthesized by the reaction of 2-hydroxypyridine and chloroacetic acid in a basic aqueous solution,and characterized by elemental analysis,IR spectrum and single crystal X-ray diffraction.The chemical formula is C_7H_7NO_3.The crystal belongs to monoclinic system with space group P2_1/c,a=0.74370(15)nm,b=0.9991(2)nm,c=0.9974(2)nm,β=110.23(3)°.V=0.6954(2)nm~3,Z=4,M_r=153.14,R=0.0383,wR=0.0962.Structural analysis indicates that the solid state of the title compound exists as a type of the ketonic configuration without a betaine.Intermolecular hydrogen bonds between carboxyl O atoms of the acetate group and carbonyl O atoms form one-dimensional folded chain structure along the b axis.
