| Popis: | The title compound, C12H9ClN4, was prepared from dichloropyridazine and tolyltetrazole in a nucleophilic biaryl coupling followed by thermal ring transformation. The molecule is essentially planar (r.m.s. deviation for all non-H atoms = 0.036 Å) and an intramolecular C—H...N hydrogen bond occurs. In the crystal, the molecules form dimers connected via π–π interactions [centroid–centroid distance = 3.699 (2) Å], which are further connected to neighbouring molecules via C—H—N bonds. The bond lengths in the pyridazine ring system indicate a strong localization of the double bonds and there is a weak C—Cl bond [1.732 (3) Å]. |
