Figure 4
The hydrogen-bonded region of the column shown in Fig. 3, including the solvent molecules and only the A or D rings of E2. Displacement ellipsoids are plotted at the 50% probability level [symmetry codes: (i) x, y, z; (ii) −x, y − , −z; (iii) −1 − x, y − , −z; (iv) 1 + x, y, 1 + z; (v) −2 − x, y − , −1 − z; (vi) x, y, 1 + z; (vii) −1 − x, y, z]. |
