✦ Synopsis
The title compound, C 36 H 58 N 2 O 3 , also known as a liquid crystalline material, has a phase sequence of crystal-smectic C-isotropic liquid. The two benzene rings are nearly coplanar with the central NNO group, and each paraffin chain has an all-trans conformation. The molecules form a tilted layer structure via intermolecular -, C-HÁ Á ÁO and C-HÁ Á Á interactions.
