Crystals of diuron, N'-(3,4-dichlorophenyl)-N,N-dimethylurea, C9H10Cl2N2O, were grown from ethanol at low supersaturation. The crystal faces were indexed using a two-circle optical goniometer and X-ray diffraction was used to orientate the crystal morphology with respect to the unit cell. The experimental morphologies were compared with the morphologies predicted by the BFDH (Bravais, Friedel, Donnay, Harker) and attachment energy (AE) methods and calculated from two crystal structures. Good agreement was obtained between experimental and theoretical habits, despite the fact that the crystals exhibit 27 faces belonging to 13 crystallographic forms.
