Figure 4From: Structures in solid state and solution of dimethoxy curcuminoids: regioselective bromination and chlorinationX-ray structure of 2e, polymorph 1. (a) ORTEP view of 2e, polymorph 1 (50% probability displacement ellipsoids). Hydrogen atoms are drawn as circles of arbitrary radii. [Symmetry code (i) –x, y, –z+12] (b) Difference-Fourier map plotted in the mean plane of labelled atoms. (c) Packing of molecules of 2e (polymorph 1) as viewed along c axis. In the channels oriented along c axis are also molecules of solvent, methanol.Back to article page
