13-Phenyl-11,13,15-triazatricyclo[8.5.2.011,15]heptadec-16-ene-12,14-dione

Abstract

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