The title compound, C(15)H(14)N(2)O(4), is an important inter-mediate for the synthesis of thermotropic liquid crystals. The dihedral angle between the two aromatic rings is 84.29 (4)°. An N-H⋯O hydrogen bond connects the mol-ecules into chains running along the b axis. In addition, the crystal packing is stabilized by weak C-H⋯O hydrogen bonds.
The asymmetric unit of the title compound, C(14)H(12)N(2)O(4), contains two mol-ecules that differ principally in the orientation of the acetamide substituent to the adjacent benzene ring with dihedral angles of 44.77 (7) and 19.06 (7)°. The dihedral angles between the benzene rings are 64.46 (4) and 80.84 (4)°. In the crystal, classical N-H⋯O hydrogen… (More)
