(4E)-1-Phenyl-4-{[(pyridin-2-yl)amino]methylidene}pyrazolidine-3,5-dione
The title compound, C15H12N4O2, contains two independent molecules in the asymmetric unit. These differ in terms of dihedral angles that the phenyl and 2-pyridyl rings subtend with the central five-membered ring; 15.2 (2) and 2.9 (2)°, respectively, in one molecule, 8.9 (2) and 5.1 (2)°for the secon...
