Synthesis, Crystal Structure and Hirshfeld Surface Analysis of 1,7-Dimethyl

Abstract

Molecules of the title compound, C16H16N2O2, occupy special positions on the twofold rotation axes. The heterocyclic ring adopts a slightly twisted envelope conformation with one of the two junction carbon atoms as the flap. The mean planes through the two halves of the molecule form a dihedral angle of 72.01 (2)degrees. In the crystal, molecules are linked by pairs of C-H center dot center dot center dot O and N-H center dot center dot center dot C contacts into layers parallel to (100). H center dot center dot center dot H contacts make the largestcontribution to the Hirshfeld surface (58.9%).
