Abstract

The structure of the triclinic polymorph of acetone 2,4-dinitrophenylhydrazone, C9H10N4O4, has been redetermined from diffraction data collected at 120 (2) K; the molecules are linked by C - (HO)-O-... hydrogen bonds into centrosymmetric R-2(2)( 10) dimers which are themselves linked into a chain by an aromatic pi-pi stacking interaction. In the monoclinic polymorph, which crystallizes with Z' = 2 in the space group P2(1)/n, one type of molecule forms dimers exactly as in the triclinic polymorph, while the other forms C(6) chains.
