Figure 1
Mixed ellipsoid and polyhedral representation of the polyoxoanion-supported lanthanum(III) complex anion, [La(W5O18)2]9−, showing the labelling scheme for selected atoms and emphasizing the square antiprismatic coordination environment for the central La3+ cation. Atoms belonging to the asymmetric unit are represented with ellipsoids drawn at the 50% probability level. [Symmetry code: (i) 2 − x, y, − z.] |
