13-Phenyl-11,13,15-triazatricyclo8.5.2.011,15heptadec-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) A, respectively. The closest intermolecular contact 3.306 (4) A is between a phenyl carbon atom and an O atom of the 1,2,4-triazoline-3,5-dione moiety.
