The new dodecanuclear organostannoxane {[(PhCH2Sn)123-O)14(μ-OH)6](F3CSO3)2} (2) has been isolated as single crystals from the reaction of trifluoromethanesulfonic acid (F3CSO3H) with the decanuclear dibenzyltin(IV)-oxo cluster, [(PhCH2)2SnO]6{[(PhCH2)2SnOH]2(CO3)}2 (1), in [D3]acetonitrile, at room temperature. Compound 2 was structurally characterized by X-ray diffraction analysis, multinuclear NMR and IR spectroscopy, mass spectrometry, and thermogravimetry. The structure of 2 can be described as a football cage framework containing twelve tin atoms, exhibiting two distinct coordination geometries, penta- and hexacoordinated respectively, and linked together through μ3-O and μ-OH ligands. Resulting from Sn-C bond cleavage, all tin atoms are only connected to one benzyl ligand. Furthermore, two of the three oxygen atoms of each trifluoromethanesulfonate counteranions are involved in hydrogen bonding interactions with bridging μ-OH groups of two distinct Sn12 cations leading to the propagation of a two-dimensional polymeric network.
