Abstract: The trans-trans conformations adopted by the derivatized bis(bidentate) chelating N₄-donor ligand 3,6-bis(pyrazol-1-yl)-4-[2-(4-thiamorpholino)ethanesulfanyl]pyridazine, C₁₆H₁₉N₇S₂, and an intermediate in its formation, 3,6-dichloro-4-[2-(4-thiamorpholino)ethanesulfanyl]pyridazine, C₁₀H₁₃Cl₂N₃S₂, contrast with the cis-cis conformation found previously for 3,6-bis(thiophen-2-yl)pyridazine [Ackers, Blake, Hill & Hubberstey (2002). Acta Cryst. C58, o640-o641], which places all four heteroatoms on the same side of the molecule.

Formula: C₁₀H₁₃Cl₂N₃S₂ and C₁₆H₁₉N₇S₂
