(a), (b) Residual density maps for the C2HO4− anion calculated either for reflections with I ≥ (a), or for all reflections (b). (c), (d) Deformation density (c) and negative Laplacian (d) maps for the same molecular fragment. Contours and colour coding: (a), (b), (c) linear 0.05 e Å−3 contours; blue solid lines – positive values, red dashed lines – negative values; (d) logarithmic contours; red solid lines – positive values, blue dashed lines – negative values. |
