Demethylation of the [Me3Sn(PhN2O2)](4) tetramer into dimeric [Me2Sn(PhN2O2)(2)](2): a thermally induced methyl-transfer between supramolecules

摘要

The single crystals of tetrameric [Me3Sn(PhN2O2)](4) (1) supramolecule demethylates into single crystals of [Me2Sn(PhN2O2)(2)](2) dimer (2) and volatile Me4Sn, as a result of a crystal-to-crystal supramolecular structural transformation, which occurs upon heating and it is accompanied by a significant change of the molecular and crystal structures.
