3,4-Dimeth-oxy-N-(4-nitro-benzyl-idene)-aniline.

ABSTRACT: In the title mol-ecule, C(15)H(14)N(2)O(4), the dihedral angle between the two benzene rings is 29.52?(8)°. The nitro and two meth-oxy substituents are almost coplanar with their respective benzene rings. The crystal structure is stabilized by inter-molecular C-H?O inter-actions.

Project description:The title compound, C(15)H(14)N(2)O(4), has two crystallographically independent mol-ecules in the asymmetric unit. In both mol-ecules, the nitro and the two meth-oxy substituents are coplanar with the benzene rings to which they are attached. The benzene rings are nearly coplanar, with dihedral angles between the two benzene rings of 10.39?(8) and 5.95?(8)° in the two mol-ecules. The two independent mol-ecules in the asymmetric unit are rotated with respect to each other such that the dihedral angles between equivalent benzene rings are 49.11?(8) and 63.93?(8)°. In the crystal structure, inter-molecular C-H?O hydrogen-bond contacts and a weak C-H?? inter-action are observed.
