Figure 1 : Molecular structure of the title compound showing the numbering scheme of the three crystallographically independent molecules (A, B, C). Displacement ellipsoids are drawn at the 50% probability level; hydrogen atoms are represented by spheres with an arbitrary radius. Hydrogen atoms of methoxy groups are denominated with a lower case suffix: a, b, c for A, d, e, f for B, and g, h, i for C. |
