Cover Picture: Cocrystallization with Acetylene: Molecular Complexes with Acetone and Dimethyl Sulfoxide (Angew. Chem. Int. Ed. 17/2003)
By in situ crystallization under pressure in a capillary, two different phases of acetylene complexes were grown simultaneously. The crystals gave the superimposed diffraction patterns shown in the background. From the reflections of the 1:1 phase (red) two cell parameters can be determined directly. In the reflections of the 1:2 phase (white) another reciprocal lattice is visible on viewing the picture from the side. For more information see the article by R. Boese et al. on page 1961 ff.
