The crystal structure of merimepodib has been solved and refined using synchrotron X-ray powder diffraction data and optimized using density functional theory techniques. Merimepodib crystallizes in space group P212121 (#19) with a = 4.60827(3), b = 12.30400(14), c = 37.9583(4) Å, V = 2152.241(20) Å3, and Z = 4. The crystal structure is dominated by two chains of N–H⋯O hydrogen bonds along the a-axis. The solid-state conformation has a similar general shape to the minimum-energy conformation, but different orientations of several of the rings. The differences indicate that intermolecular interactions are important in determining the solid-state conformation. The powder pattern has been submitted to ICDD for inclusion in the Powder Diffraction File™ (PDF®).
