| Abstract: | Preparation, Mössbauer and Vibrational Spectra of the Complexes SnCl4F]?, SnCl4(NCS)]?, and SnCl4(NCS)2]2? N(CH2)4F and N(CH2)4SCN react in liquid SO2 with SnCl4 yielding the adducts N(CH3)4]SnCl4F] (I), N(CH3)4]SnCl4(NCS)] (II) and N(CH3)4]2SnCl4(NCS)2] (III).respectively. Mössbauer and vibrational spectra indicate for the anion of I a fluoro-bridged species, which is probably tetrameric like the isoelectronic SbCl4F. For II dimeric moieties are proposed with bridging S-atoms, while SnCl4(NCS)2]2? has an octahedral structure with N-bonded isothiocyanate groups in the trans-positions. |
