Dimethyl 4,4′-(diazenedi­yl)dibenzoate at 100 K

In the asymmetric part of the unit cell of the title compound, C(16)H(14)N(2)O(4), there are two chemically equivalent but crystallographic independent half mol­ecules. The geometric centre of each complete mol­ecule lies on a crystallographic inversion centre. Both mol­ecules 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, mol­ecules are arranged in columns along the a axis. There are no inter­molecular donor–acceptor distances shorter than 3.4 Å.
