چکیده
The title compound, C(30)H(36)N(2)O(6), was prepared via twofold Suzuki coupling of a diboronic acid with bromo-nitro-benzene. The mol-ecule is located on a crystallographic inversion centre. The lateral benzene ring and the central ring make a dihedral angle of 48.75 (14)° and the nitro group is twisted by 41.47 (13)° out of the plane of the benzene ring. The nitro and hex-yloxy groups are in close proximity and the hex-yloxy chain adopts an all-anti conformation.

The title structure, C(22)H(24)N(2)O(10), contains two independent centrosymmetric mol-ecules. The only significant difference between the mol-ecules is the dihedral angle between the unique carbonate group (-O-CO(2)-) and the benzene ring, the values being 77.35 (8) and 66.42 (8)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

In the centrosymmetric title compound, C(18)H(28)Br(2)O(2), the alkyl chains adopt a fully extended all-trans conformation and each of them is almost planar. In addition, the alkyl chains are coplanar with the benzene ring. Inter-molecular Br⋯Br inter-actions [3.410 (3) Å] are present, resulting in a one-dimensional supra-molecular architecture.
