A similar reaction between L2H [3-{N9-(2-amino­purinyl)}­propanoic acid] with (Ph<sub>3</sub>Sn)<sub>2</sub>O in a 2:1 ratio afforded a dimer [(L2)­(Ph<sub>3</sub>Sn)­L2­{Ph<sub>3</sub>Sn­(H<sub>2</sub>O)}]·​3CH<sub>3</sub>OH·​3H<sub>2</sub>O (<b>3</b>). The reactions of 2-(N9-adeninyl)­acetic acid (L3H) and 3-(N9-adeninyl)­propanoic acid (L4H) with (Ph<sub>3</sub>Sn)<sub>2</sub>O in a 2:1 ratio afforded insoluble intractable products, which, upon addition of dilute HCl in methanol, afforded [{Ph<sub>2</sub>SnCl<sub>3</sub>­(H<sub>2</sub>O)}­(HL3Me)<sub>2</sub>Cl]·​H<sub>2</sub>O (<b>4</b>) and [(Ph<sub>2</sub>SnCl<sub>4</sub>)­(HL4Me)<sub>2</sub>] (<b>5</b>). Complexes <b>1</b>–<b>5</b> show an extensive supramolecular organization in the solid state as a result of several intermolecular interactions, prominent among which are the interactions between the nucleobases.
