(E)-N-[4-(Di­ethyl­amino)-2-hy­droxy­benzyl­idene]-2,4,6-tri­methyl­benzenaminium nitrate

The crystal structure of a protonated Schiff base, isolated as its nitrate salt, exhibits a supra­molecular chain-like architecture that propagates along the crystallographic b-axis direction and features inter­molecular O—H⋯O and C—H⋯O hydrogen-bonding.
