Figure 1
The structure of (II), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 40% probability level and H atoms are shown as small spheres of equal though arbitrary radii. The O atoms of the fractionally occupied methanol and water solvent molecules share the same site (O1S) and are hydrogen bonded to atom O4 via atom H1S (shared site). The partially occupied methanol atom C1S is shown with an open bond to atom O1S. The methyl-group H atoms were not located in the difference Fourier map. |
