Abstract

Titanium reduced oxides TiO2-x occupy, since long time, a prominent place on the landscape of binary metal oxides because of their intriguing ability to form extended defects that affect both the formation of new superlattices and different electronic behaviours. Related to these features, a wide range of practical applications has been achieved. Moved by the conviction of the great potential of understanding the influence of the reactivity, compositional variations and size effects on their functional properties, the aim of this personal account is the optimization of a recently developed strategy for the stabilization of low n Tin O2n-1 terms. In particular, we will focus on the Ti4 O7 composition as well as the incorporation of transition metals, like Mn, in order to deal with new reduced Magneli phases.

Abstract

Pulsed field gradient 1 H NMR spectroscopy has been applied to investigate the association behavior of the Sn 1 2 -oxo cluster macrocation [(BuSn) 1 2 O 1 4 (OH) 6 ] 2 + with two different and smaller anions, p-toluenesulfonate (PTS - ) and diphenylphosphinate (Ph 2 PO 2 -). By monitoring the translational diffusion coefficients of the various species involved, it is shown that the association depends on the anion involved and on the solvent used. Moreover, the possibility to individually monitor the diffusion characteristics of multiple anionic and cationic species in mixtures, by virtue of resolved 1 H resonances available from each species, allows us to evidence the occurrence of ion exchange in such systems. Thus when [(BuSn) 1 2 O 1 4 (OH) 6 ](PTS) 2 is mixed with two equivalents of Ph 2 PO 2 NMe 4 , PTS- is displaced by Ph 2 PO 2 -, highlighting the greater affinity of the organotin macrocation for the diphenylphosphinate. This example clearly illustrates the potential of pulsed field gradient 1 H NMR spectroscopy in inorganic/organometallic chemistry, to follow preferential ion pairing in multi-ion systems at the level of each individually charged species.
