Figure 1
The molecular structure of (I), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level and H atoms have been omitted for clarity. Both positions of disordered carboxylate atoms O3 and O4 are shown. [Symmetry codes: (i) −x, −y, −z; (ii) −x + 1, y − , −z + .] |
