N2 - The study presents the synthesis and structural aspects of a new family of dimethyltin carboxylates, [(Me2Sn)2(btec)(bipy)(H2O)] ⋅ 4H2O (1), [Me2Sn(btec)0.5(bipy)]2 ⋅ H2O (2), [Me2Sn(btec)0.5(bipy)] ⋅ 3H2O ⋅ 0.5bipy (3) and [Me2Sn(btec)0.5(phen)] (4) derived from 1,2,4,5-benzenetetracarboxylic acid (H4btec). The structure in each case adopts a one-dimensional motif featuring ditin macrocycles with 2,2'-bipyridine (bipy) or 1,10-phenanthroline (phen) acting as the chelating ligand. For 1, the lattice water molecules in association with the framework form infinite T4(0)A(1) water chains. The organic hydrate, bipy ⋅ 6H2O in 3 adopts a layered structure comprising T4(2)6(2) water tapes and trans-bipy. Dehydration of 2 to 2 a results in crystal structure transformation from centrosymmetric P21/c (in 2) to chiral P212121 space group and reveals conformational changes in the ditin macrocycles from chair to boat form. The reversibility of this transformation has been supported by TGA, PXRD, and single-crystal X-ray studies.
