A convenient and quantitative route to Sn(iv)-M [M = Ti(iv), Nb(v), Ta(v)] heterobimetallic precursors for dense mixed-metal oxide ceramicsElectronic supplementary information (ESI) available: FT-IR, 1H and 119Sn NMR spectra of the new complexes, molecular structures with selected bond lengths (Å) and angles (°) of 1a, 1b, 4a, 6 and 8, DFT-optimized structures of 4-6 and related model compounds, dilatograms related to the Spark Plasma Sintering of the pre-calcined Sn0.5Ti0.5O2 powders, and 9 X-r
The strategy of reacting SnCl 4 with M(OR) x provided a convenient and quantitative approach to new heterobimetallics with a simple addition formula, [SnCl 4 M(OR) x (HOR) y ] (M = Ti, Nb, Ta; R = Et, Pr i , x = 4, 5; y = 0-2) or sometimes an oxo complex [SnCl 3 (O)Ti 2 (OPr i ) 7 (HOPr i ) 2 ]. The...
