(a) The structure of 10, showing the K—O layer, indicating the bridging carboxylate units and the location of the O⋯H⋯O SSHB interactions (shown as black and white bonds); H and C atoms in the arene rings have been omitted. (b) The organic ligands arranged in parallel stacks and (c) the packing arrangement, viewed down the b axis, showing the bilayer motif; H atoms on the arene rings and water molecules have been omitted. For clarity, the disorder in the water molecules located between adjacent hydrophobic regions is not shown. Colour code: K blue, carboxylate and phenolate O red, water O green, C black and H pale pink. |
