Figure 2
Observed Fourier maps of the electron-density distribution in the neighborhood of the copper sites for the layers (x1, x4), based (a) in model 3; (b) in model 4; (c) in model 2. Refined atomic coordinates are marked by solid lines. Lines in (a) indicate Cu and Cu′ with an occupancy above 50%. Contour intervals are 2 e Å−3. |
