Figure 2
The coordination pattern in (I). Lanthanum ions and water O atoms are depicted as small spheres. (a) A fragment of the coordination network around the marked inversion center at (0, 0, 0). O atoms marked with an asterisk belong to neighboring dicarboxylate entities. [Symmetry codes: (i) −x, −y + 1, −z; (ii) −x, −y, −z; (iii) −x + 1, −y, −z.] (b) An extended face-on view of the coordination network, aligned parallel to the ab plane and centered at z = 0. H atoms have been omitted. |
