Figure 6
The electron-density distributions around the atoms Bi41 and Bi42 in x1 − x4 constructed from the diffraction pattern including the satellite reflections. The contour lines symbolize steps within 20 e Å−3. The bold lines represent the fit of the atomic positions according to the introduced sawtooth functions. In the upper [lower] part of this picture the sequence 5(A) + 3(B) [4(A) + 4(B)] is shown. |
