Reactions of (<i>E</i>)‑5-(Pyridin-4-yl-methyleneamino)isophthalic Acid (LH₂) with Triorganotin Oxides and −Chloride. Formation of One-Dimensional- and Two-Dimensional-Coordination Polymers

Abstract

The reaction of (n-Bu3Sn)2O with (E)-5-(pyridin-4-yl-methyleneamino)­isophthalic acid (LH2) in a stoichiometric ratio of 1:1 resulted in the formation of a 2D coordination polymer [(n-Bu3Sn)2(μ-L)]n (1). The structure of 1 contains a 36-membered macrocycle as its repeating building block. The reactions of Me3SnCl or (Ph3Sn)2O with LH2, on the other hand, result in the generation of [(Me3Sn)2(μ-L)­(H2O)]n (a neutral 1D coordination polymer) (2) and [(Ph3Sn)­(μ-L)­(Et3NH)]n (an anionic 1D coordination polymer) (3), respectively. Compounds 1–3 show a rich supramolecular architecture in their solid state as a result of multiple secondary interactions
