Figure 7
The structure of Rb₂(H₃thba)₂(H₂O) (3) (a) in a view down the c axis, showing the interleaved layers of anions and metal centres that resemble a millefeuille pastry (right), (b) with H₃thba⁻ units forming a plane containing chains linked by hydrogen bonding and (c) with the H₃thba⁻ units stacked in an antiparallel face-to-face manner in the direction of the b axis. Colour code: Rb purple, carboxylate and hydroxy O red, water O green, C black and H pale pink.
