Spectroscopic properties of microporous layered tin sulfide materials

Abstract

¹¹⁹ Sn solid state nuclear magnetic resonance, ¹¹⁹Sn Mössbauer, Fourier transform Raman and variable temperature single crystal UV–VIS absorption, emission and excitation spectra of some archetypal microporous layered tin sulfides, denoted (Et₄N)₂Sn₃S₇ (TEA-SnS-1), (C₆H₁₂N₂H)₂Sn₃S₇ (DABCOH-SnS-1), (NH₄)_0.5(Et₄N)₁ .₅Sn₃S₇ (ATEA-SnS-1) and (Pr₄N)₂Sn₄S₉ (TPA-SnS-3), are reported. The combined spectroscopic results provide a rather comprehensive picture of structure–property relations for this novel class of solids, which have the unusual ability of being able to behave as both molecular sieve and intercalation materials to a range of guests.
