Crystal structure of 3-methxybenzanthrone from x-ray powder diffraction

摘要

In the framework of the study of the relationship between crystal packing of solid dyes and their visible reflectance spectra, the crystal structure of 3-methoxy-7H-benz[de] anthracen-7-one (Disperse Yellow 13, C_18H_12O_2) has been determined using a combined set of Bragg-Brentano diffractometer and Guinier-Johannson photographic data with the grid search procedure.
