Abstract

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.
