Abstract

Mol­ecules of methyl 3,5-dinitro­benzoate, C8H6N2O6, are linked into C(7) chains by a single nearly linear C-H...O hydrogen bond, but there are no direction-specific inter­actions in the structure of isopropyl 3,5-dinitro­benzoate, C10H10N2O6. In benzyl 3,5-dinitro­benzoate, C14H10N2O6, the mol­ecules are linked by four independent C-H...O hydrogen bonds into a complex three-dimensional framework structure, in which it is possible to identify simple substructures in the form of cyclic centrosymmetric dimers, double helices and sextuple helices.
