The first mixed-valence fluorotin alkoxides: New sol-gel precursors of fluorine-doped tin oxide materials

摘要

New mixed-valence fluorotin alkoxides; (SnSnF2)-Sn-II-F-IV(OR)(4) 1 (R = tett-butyl, tert-amyl) were synthesized and characterized by multinuclear NMR and Mossbauer spectroscopies. The two tin sites are bridged via three mu(2)(OR) groups. Adducts 1 yielded nanocrystalline conductive F-doped SnO2 powders by the sol-gel process. [GRAPHICS] [References: 34]
