Figure 2
(xs1, xs4)-sections of difference-Fourier maps centered on the Rb2 atom (x1 = 0.25, x2 = 0.819 and x3 = 0.487) from different models, showing two periods along xs4. Solid lines represent positive values, dashed lines are negative values, and long dashed lines represent the zero contour. The contour interval is 0.2 e Å-3. Maximum and minimum values over the map are 3.63/−0.57 e Å-3 for model A, 2.12/−0.41 e Å-3 for model B, 1.35/−0.52 e Å-3 for model Cr, 0.93/−0.51 e Å-3 for model Dr. The thick (red) lines denote the modulated position of the Rb2 atom. |
