The bond angle at the bridging O atom between the two subunits of the title compound, C 15 H 18 NO 2 , is 114.1 (5) , which exceeds the values reported for structurally related 1-(alkoxy)pyridin-2(1H)-ones. The pyridone ring and the alkoxy substituent are located on a mirror plane so that the carbon
The title compound, C 16 H 10 Cl 2 N 4 O, has been synthesized as a potent fungicidal agent and plant growth regulatory agent, and its crystal structure was determined. In the crystal structure, weak intermolecular C-HÁ Á ÁCl interactions are found. The dihedral angles between the planes of the pyri
The molecule of the title compound, C 16 H 12 N 2 O 2 , is nearly planar, and adopts the keto±amine tautomeric form with an intramolecular NÐHÁ Á ÁO hydrogen bond. The molecules are linked by OÐHÁ Á ÁO hydrogen bonds into a three-dimensional network.
