Di­methyl (1‐methyl‐1,3‐benzimidazol‐5‐yl)­amino­methyl­ene­propane­dioate monohydrate

In the title compound, C₁₄H₁₅N₃O₄·H₂O, there is a strong conjugation push–pull effect across the central double bond, as reflected in the molecular dimensions and the planarity of the en­amino­ne portion of the mol­ecule. The mol­ecule has an intramolecular hydrogen bond between the NH and CO groups in the Z configuration, adopting the chelated form. The two π systems of the mol­ecule (1‐methyl­benz­imidazole and en­amino­ne) are deconjugated and tilted with respect to each other by 15.6 (2)°. The solvent water mol­ecule is hydrogen bonded to the N¹ atom of the 1‐methyl­benzimidazolyl group.
