Abstract
The
reaction of (<i>n</i>-Bu<sub>3</sub>Sn)<sub>2</sub>O with
(<i>E</i>)-5-(pyridin-4-yl-methyleneamino)isophthalic
acid (LH<sub>2</sub>) in a stoichiometric ratio of 1:1 resulted in
the formation of a 2D coordination polymer [(<i>n</i>-Bu<sub>3</sub>Sn)<sub>2</sub>(μ-L)]<sub><i>n</i></sub> (<b>1</b>). The structure of <b>1</b> contains a 36-membered
macrocycle as its repeating building block. The reactions of Me<sub>3</sub>SnCl or (Ph<sub>3</sub>Sn)<sub>2</sub>O with LH<sub>2</sub>, on the other hand, result in the generation of [(Me<sub>3</sub>Sn)<sub>2</sub>(μ-L)(H<sub>2</sub>O)]<sub><i>n</i></sub> (a neutral 1D coordination polymer) (<b>2</b>) and [(Ph<sub>3</sub>Sn)(μ-L)(Et<sub>3</sub>NH)]<sub><i>n</i></sub> (an anionic 1D coordination polymer) (<b>3</b>), respectively.
Compounds <b>1</b>–<b>3</b> show a rich supramolecular
architecture in their solid state as a result of multiple secondary
interactions
