The structure of Pb(H3thba)2(H2O) (20), showing (a) bonding around the lead centre (noncovalent interactions are indicated by blue and white connections) and (b) the stacks of H3thba− units, viewed down the a axis, held together by π–π interactions. Hydrogen bonds have been omitted for clarity. Colour code: Pb green, O red, C black and H pale pink. |
