The effect of molecular planarity on crystal non-centrosymmetry in benzylidene-aniline derivatives.

ABSTRACT

In the title compound, N-(2-methoxyphenyl)-4-nitrobenzylideneamine, C(14)H(12)N(2)O(3), the two phenyl rings make a dihedral angle of 48.0 (2) degrees and the nitro group is at an angle of 6.5 (1) degrees with respect to its attached phenyl ring. In the crystal structure, molecules are related as centrosymmetric pairs through pi-pi interactions and are further connected through strong C[bond]H...O hydrogen bonds [C...O 3.4259 (17) A and C[bond]H...O 167 degrees ], forming molecular stacks along [100]. These stacks associate further through longer C[bond]H...O interactions, forming two-dimensional networks. In the c direction, there are only weak van der Waals interactions. The relationship between the molecular planarity and its centrosymmetry is also briefly described.
