Abstract

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 = R2P(CH2)(2)-PR2, R = Me, Et, Ph or Cy; o-C6H4(PR2)(2), R = Me or Ph] and characterised by IR and multinuclear NMR (H-1, F-19, (31)p, Sn-119) spectroscopy. The crystal structures of trans[SnF4(PCy3)(2)] and cis-[SnF4{Et2P(CH2)(2)PEt2}] are reported. Tin(IV) fluoride complexes of 2,2'-bipyridyl, 1,10-phenanthroline, MeO(CH2)(2)OMe, Me2N(CH2)(2)NMe2, pyridine and THF have been characterised by multinuclear NMR spectroscopy, the structures of cis-{SnF4(L-L)] (L-L = 1,10-phenanthroline and MeO(CH2)(2)OMe} determined, and the properties were compared with those of the phosphane complexes. Complexes of o-C6H4(PMe2)(2), Et(2)p(CH2)(2)PEt2, and MeC(CH2AsMe2)(3) with SnCl4 and SnBr4 are also reported and the structures of cis-[SnCl4{Et(2)p(CH2)(2)PEt2}] and cis-[SnBr4{kappa(2)-MeC(CH2AsMe2)(3)}] described. Attempts to prepare tertiary arsane complexes of SnF4 have been unsuccessful.
