Figure 1
The seven molecules in the asymmetric unit of MA, with the atomic numbering schemes. Displacement ellipsoids and spheres are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. For molecule A, six alternative side-chain orientations are shown; a thick black line (to atom C41A) is used for the most populated orientation (A1; see Table 1). For molecule B, there is disorder at C6B—C7B; the major component [occupancy 0.609 (18)] is shown with open bonds and the minor component as a stick drawing. |
