The
reaction of L1H [L1H = 3-(N9-hypoxanthyl)propanoic acid]
with Me<sub>3</sub>SnCl or (<i>n</i>-Bu<sub>3</sub>Sn)<sub>2</sub>O afforded the 1D coordination polymers [Me<sub>3</sub>Sn(L1)]<i><sub>n</sub></i> (<b>1</b>) and [<i>n</i>-Bu<sub>3</sub>Sn(L1)]<i><sub>n</sub></i> (<b>2</b>), respectively.
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.
