B. Gao

Abstract: Molecules of the title compound, C4H4ClN3, are essentially planar. N-H...N hydrogen bonds link the molecules into a two-dimensional network parallel to the (100) plane. The pyridazine rings of inversion-related molecules are stacked with their centroids separated by a distance of 3.7597 (10) Å, indicating [pi]-[pi] interactions.
