The structures of the two independent molecules of (I), with the atom-numbering schemes. Displacement ellipsoids are drawn at the 50% probability level. Molecule A is at the top and molecule B at the bottom. Unlabelled atoms are related to labelled atoms by the symmetry operator (1 − x, y, −z) in molecule A and by (1 − x, y, 1 − z) in molecule B. |
