Figure 1
The coordination environment of the LaIII ion in (I), showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 50% probability level at 110 (2) K and H atoms are shown as small spheres of arbitrary radii. Hydrogen bonds to the noncoordinated water molecules are indicated by dashed lines. The oxalate ligand is located on a crystallographic inversion centre at (, 0, 0).
