Abstract: In the title compound, C₂₀H₁₈N₂O₈, the coumarin moiety is oriented approximately perpendicular to the plane of the pyrazole ring. Weak intermolecular C-HO interactions link the molecules into a complex network that can be represented by C(X) chains (X is 8, 10, 11 and 13) and R₂²(26) and R₂²(10) rings.
