On the industrial scale, they have a wide range of applications, such as dyes and pigments (Taggi et al., 2002). Schiff bases have also been employed as ligands for the complexation of metal ions (Aydoğan et al., 2001).
The molecular structure of the title compound is shown on Fig. 1. The dihedral angle between the C10-C13/S1 nitrothiophene and the C1-C6 phenyl ring is 27.94 (13)°. The deviation from planarity may be due to steric repulsion between the methylene group and phenyl ring. The length of the C5=N2 double bond is 1.266 (3) Å, slightly shorter than standard 1.28 Å value of a C=N double bond and consistent with related structures (Ağar et al., 2010;Tanak et al., 2009;Ceylan et al., 2011).

Refinement
H atoms were positioned geometrically and refined using a riding model, with C-H = 0.93-0.96 Å and U iso (H) = 1.2-1.5U eq (C).  Refinement. Refinement of F 2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F 2 , conventional R-factors R are based on F, with F set to zero for negative F 2 . The threshold expression of F 2 > σ(F 2 ) is used only for calculating Rfactors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
