(E)-5,5'-(Diazene-1,2-di-yl)diisophthalic acid N,N-dimethyl-formamide disolvate.


ABSTRACT: The title compound, C(16)H(10)N(2)O(8)·2C(3)H(7)NO, was synthesized by the reductive condensation reaction of 5-nitro-isophthalic acid in the presence of NaOH. The tetra-acid mol-ecule, which has a crystallographically imposed centre of symmetry, adopts an E configuration with respect to the azo group. In the crystal packing, mol-ecules are linked through inter-molecular O-H?O and C-H?O hydrogen-bonding inter-actions, forming chains propagating in [20].
