Rule, Not Exclusion: Formation of Dichlorine-Containing Supramolecular Complexes with Chlorometalates(IV)

Abstract

Supramolecular derivatives of chlorostannate(IV) and -plumbate(IV) with {Cl₂} units, Cat₂{[MCl₆](Cl₂)_<i>x</i>} (<b>1</b>-<b>5</b>; M = Sn, Pb, cat = 1-methylpyridinium (1-MePy), tetramethylammonium (TMA)) were prepared and characterized by X-ray diffractometry and Raman spectroscopy. In particular, the TMA-containing complexes demonstrate remarkable thermal stability, releasing Cl₂ only at elevated temperatures.
