The title compound, C20H25N3O2, has been assigned an endo structure on the basis of its X-ray analysis.In the N-phenyl-1,2,4-triazoline-3,5-dione moiety, the N-N and average C-O bond distances have values of 1.424(3) and 1.208(2)Angstrom A, respectively. The closest intermolecular contact of 3.306(4)Angstrom A is between a phenyl C atom and an O atom of the 1,2,4-triazoline-3,5-dione moiety.
