3,4,5-Trihydroxy-N′-(1H-indol-2-ylmethylidene)benzohydrazide–1H-indole-2-carbaldehyde azine–methanol (2/1/2)

3,4,5-Trihydroxy-N′-(1H-indol-2-ylmethylidene)benzohydrazide–1H-indole-2-carbaldehyde azine–methanol (2/1/2)

The title compound, 2C16H13N3O4·C18H14N4·2CH4O, was crystallized from the reaction between 3,4,5-trihydroxybenzoylhydrazine and indole-2-carbaldehyde in a mixture of ethanol and methanol. The compound is a stoichiometric 2:1 cocrystal of the methanol-solvated reaction produ...
