The structure of 7, showing (a) the Rb—O layer, viewed along the a axis; C atoms in the arene rings and H atoms have been omitted. (b) The stacking of the Hhba− ligands, similar to that seen in compound 5; the centroids of the face-to-face pairs are approximately 3.83 Å apart. (c) The packing arrangement, viewed down the b axis, with H atoms omitted. Colour code: Rb purple, carboxylate and phenolate O red, water O green, C black and H pale pink. |
