Solid State Synthesis and Characterization of Tin-Based Low-Dimensional Materials

We report the synthetic conditions, physical properties and potential applications of late group 14 metal (Sn) 0D, 1D, 2D and 3D extended materials. The structures are primarily neutral chain and anionic layered compounds. The latter are charge-balanced by ammonium cations, as in and BING-7 [Sn(C 2 O 4 )F - ] [NH 4 + ] and BING-8 [Sn(PO 4 H)F - ] [NH 4 + ]. The neutral layered compound and chain compounds BING-1 [Na 4 Sn 4 (C 2 O 4 )F 6 ], BING-2 [KSn(C 2 O 4 )F] and BING-4 [Sn(C 2 O 4 )(C 5 H 5 N)] have also been synthesized solvothermally. Thermogravimetric analysis (TGA) under nitrogen and in-situ variable temperature X-ray diffraction show that the materials decompose in the 200°C to 300°C range to more stable phases. Nuclear magnetic resonance (NMR) was used to monitor the ion-exchange properties of some of the materials. The intercalation properties of these materials are still being investigated.
