1-(6-Amino-1,3-benzodioxol-5-yl)-3-(4-pyrid­yl)prop-2-en-1-one crystallizes with Z' = 2: hydrogen-bonded supra­molecular substructures in one and two dimensions, each containing only one type of mol­ecule

The title compound, C₁₅H₁₂N₂O₃, crystallizes with Z' = 2 in the space group P and the intra­molecular dimensions show evidence for a polarized mol­ecular-electronic structure. Each of the two independent types of mol­ecule forms its own hydrogen-bonded supra­molecular substructure, and these are entirely different from one another: one type of mol­ecule forms a chain of edge-fused rings, while the other type forms sheets.
