Figure 6
Residual electron density and standard error maps after the multipole refinement (Fobs-Fmulti). All measured reflections were used in the Fourier summation. (a) Residual map of X1, (b) standard error map of X1, (c) residual map of X2, and (d) standard error map of X2. Contour levels of the residual maps are at 0.05 e Å−3, full contours show positive levels and dashed contours negative levels. The zero contours have been omitted for clarity. The contours in the standard error maps of the residual density start at 0.05 e Å−3 with increments of 0.01 e Å−3. |
