Figure 1
View of the components of (I), with the atoms of the asymmetric unit labelled; non-acidic H atoms have been omitted for clarity. Displacement ellipsoids are drawn at the 30% probability level. In the left-hand neutral molecule unlabelled atoms are related to labelled atoms by 1 − x, −y, −z. In the right-hand neutral molecule unlabelled atoms are related to labelled atoms by −x, −y, 1 − z. |
