Figure 1
The mol­ecular structure of the title compound, showing the atom-labelling scheme. Displacement ellipsods are drawn at the 50% probability level at ca 110 K. The mol­ecule resides on a special 2/m position and the asymmetric unit consists of only one quarter of the molecule. H atoms have been omitted, except those of the carboxyl groups.
