The first phosphane complexes of the hard Lewis acid SnF4 have been synthesised including trans-[SnF4(PR3)2] (R = Me or Cy) and cis-[SnF4(diphosphane)] [diphosphane = R 2P(CH2)2-PR2, R = Me, Et, Ph or Cy; o-C6H4(PR2)2, R = Me or Ph] and characterised by IR and multinuclear NMR (1H, 19F, 31P, 119Sn) spectroscopy. The crystal structures of trans-[SnF4(PCy3)2] and cis-[SnF 4{Et2P(CH2)2PEt2}] are reported. Tin(IV) fluoride complexes of 2,2′-bipyridyl, 1,10-phenanthroline, MeO(CH2)2OMe, Me2N(CH 2)2NMe2, pyridine and THF have been characterised by multinuclear NMR spectroscopy, the structures of cis-[SnF 4(L-L)] (L-L = 1,10-phenanthroline and MeO(CH2) 2OMe) determined, and the properties were compared with those of the phosphane complexes. Complexes of o-C6H4(PMe 2)2, Et2P(CH2)2PEt 2, and MeC(CH2AsMe2)3 with SnCl 4 and SnBr4 are also reported and the structures of cis-[SnCl4{Et2P(CH2)2PEt 2}] and cis-[SnBr4{κ2-MeC(CH 2AsMe2)3}] described. Attempts to prepare tertiary arsane complexes of SnF4 have been unsuccessful. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
