Abstract:
In the asymmetric part of the unit cell of the title compound, C16H14N2O4, there are two chemically equivalent but crystallographic independent half mol-ecules. The geometric centre of each complete mol-ecule lies on a crystallographic inversion centre. Both mol-ecules are almost planar [mean deviations of atoms in the two molecules are 0.032 (2) and 0.044 (2) Å] and their geometries are similar. In the crystal, mol-ecules are arranged in columns along the a axis. There are no inter-molecular donor-acceptor distances shorter than 3.4 Å.

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is...
