SPECTROSCOPIC PROPERTIES OF MICROPOROUS LAYERED TIN SULFIDE MATERIALS

Sn-119 solid state nuclear magnetic resonance, Sn-119 Mossbauer, Fouri er transform Raman and variable temperature single crystal W-VIS absor ption, emission and excitation spectra of some archetypal microporous layered tin sulfides, denoted (Et4N)(2)Sn3S7 (TEA-SnS-1), (C6H12N2H)(2 )Sn3S7 (DABCOH-SnS-1), (NH4)(0.5)(Et4N)(1-5)Sn3S7 (ATEA-SnS-1) and (Pr 4N)(2)Sn4S9 (TPA-SnS-3), are reported. The combined spectroscopic resu lts provide a rather comprehensive picture of structure-property relat ions for this novel class of solids, which have the unusual ability of being able to behave as both molecular sieve and intercalation materi als to a range of guests.
