swer this question. X-ray analysis shows that the double bond C 1=C2 and Ν1, N2 and S1 are coplanar. The planar nitro group is slightly twisted out of the molecular plan (C1-C2-N2-02: 173.9°). The phenyl ring is twisted out of this plan with a torsion angle close to 75° around the Nl-Cl bond. The both phenyl ring and its methoxy group are coplanar together. The atoms N2-C2-C1-N1 are coplanar (torsion angle value 0.1 °) wich implies that the double bond is (£)-configured. The observed torsion
