Figure 10
The crystal structures of (a) NaOEt·2EtOH (space group P21/c, view direction [010] and displacement ellipsoids at the 50% probability level) and (b) NaOnPr·2nPrOH (space group C2/c, view direction [00]). Selected symmetry elements are shown. In both structures, there is a 21 screw axis in the middle of each chain. |
