Figure 4
The Laplacian of electron density in the (100) plane of the unit cell: (a) model electron density derived from the X-ray diffraction experiment; (b) B3LYP/cc-pvDZ/CRYSTAL calculation (1); (c) B3LYP/cc-pvDZ/CRYSTAL calculation (2) – see text for explanations. Solid and broken lines represent negative and positive Laplacian values. Line intervals are ± 2 × 10n, ± 4 × 10n and ± 8 × 10n e Å−5 (−2 ≤ n ≤ 2).
