%X The crystal structure of dunnione p-bromophenylhydrazone has been determined by single-crystal X-ray diffraction methods at 295 K, the structure being refined to a residual of 0.054 for 1429 'observed' reflections. Crystals are triclinic, P&#299;, a 15.620(8), b 8.804(4), c 7.439(4) &#506;, &#945; 68.03(4), &#946; 89.85(4), &#947; 77.44(4)&#176;, Z 2. The conjugation throughout the molecule is extensive and the crystal packing is dominated by intermolecular charge-transfer interactions. Bonding in the hydrazone moiety lies intermediate between those expected for hydrazone and azo forms.
