A new class of inward-facing bis(dpp-ligands) fused to rigid molecular racks are reported, eg 17 and 19. The 3,6-di(2-pyridyl)pyridazine ligand units are formed by the reaction of 3,6-di(2-pyridyl)s-tetrazine with molrac bis(olefins), eg 11 and 18 (followed by oxidation of the intermediate dihydropyridazines); additionally mono-olefin, mono-pyridazines 14 and 21 are reported.
