Figure 7
The Laplacian of the electron density in crystals (1), (2) and (3) obtained from the experimental and theoretical structure factors using the multipole model: (a) the planes through the C2—C5—C6 atoms in which the Laplacian is depicted; (b) experimental Laplacian map; (c) theoretical Laplacian map. Red solid lines denote the areas of electron-density concentration [ < 0] and blue dashed lines correspond to electron density depletion. Contour intervals are ±2, 4, 8 × 10n e Å−5 (n = −3 to 2). |
