Bis[2,2′-ethylenedioxydibenzaldehyde bis(thiocarbohydrazide)] tris(pyridine) solvate

The title compound, a novel 30-membered 2:2 macrocyclic thio­carbohydrazone, C₃₄H₃₂N₈O₄S₂·3C₅H₅N, has been pre­pared and crystallographically characterized. The mol­ecule of the compound is twisted. One dioxa­butane group is boat-like in shape, whereas the other is highly disordered. The crystal structure is stabilized by inter- and intramolecular hydrogen bonds.
