Figure 5
The molecular structure of compound (III), showing the atom-labelling scheme. The lanthanide ion La1 and coordinated water atom O2 reside on an axis of twofold rotation at (, , z), and only atoms of the asymmetric unit are labelled. Displacement ellipsoids are drawn at the 50% probability level at ca 110 K. H atoms have been omitted, except for those involved in the intramolecular hydrogen bond (dashed lines). The disordered noncoordinated water solvent has also been omitted. |
