title: 1,4-Bis(2-nitro-phen-oxy)butane.
abstract: The asymmetric unit of the title compound, C(16)H(16)N(2)O(6), contains one-half mol-ecule, the mid-point of the central C-C bond being located on a crystallographic inversion center. The crystal structure shows weak inter-actions between the O atoms of the nitro groups and two different C-H groups of the benzene rings. The extended weak hydrogen-bond formation, involving the NO(2) groups, generates an infinite three-dimensional network.
