N2  - The crystal structures of the hemi-ethanolate of nitron, C20H16N4(C2H6O)0.5, and of a non-stoichiometric hydrochloride of nitron, C20H16N4(HCl)1.7(H2O)3.3, have been determined by X-ray diffraction from diffractometer data at 295 K and refined by block diagonal least squares to residuals of 0.069 (2049 'observed' reflections) and 0.055 (1915), respectively. Crystals of the hemi-ethanolate of nitron are monoclinic P21/n, a 12.697(6), b 15.821(5), c 19.064(6) &#506;, &#946; 108.79(3)&#176;, Z 8. Crystals of the non-stoichiometric hydrochloride of nitron are also monoclinic C2/c, a 25.41(1), b 5.968(6), c 29.40(2) &#506;, &#946; 103.53(5)&#176;, Z 8. Despite some unusual features in their molecular geometry, these structures are consistent with the mesoionic character of nitron.
