Crystal structure of 3-{1-[(1-allyl-1H-indazol-6-yl)amino]ethylidene}-6-methyl-2H-pyran-2,4(3H)-dione

In the title compound, C18H17N3O3, the dihedral angle between the planes of the indazole ring system [maximum deviation = 0.012 (1) Å] and the pyran-2,4-dione ring is 54.03 (6)°. An intramolecular N—H...O hydrogen bond closes an S(6) ring. The same H atom also participates in an intermolecular N—H.....

Description
Summary:In the title compound, C18H17N3O3, the dihedral angle between the planes of the indazole ring system [maximum deviation = 0.012 (1) Å] and the pyran-2,4-dione ring is 54.03 (6)°. An intramolecular N—H...O hydrogen bond closes an S(6) ring. The same H atom also participates in an intermolecular N—H...O hydrogen bond, which generates an inversion dimer. The dimers are linked by weak C—H...O contacts, thereby forming a three-dimensional network.
