An extended X-ray absorption fine structure (EXAFS) investigation of the metal co-ordination geometry in the cations [PtF(PR3)3]+ (R 4;= 4;Et or Ph) indicates that the Pt–F bond lengths are identical and only slightly longer than those typical for low-valent metal fluoride complexes. The solution decomposition of the complexes, [PtF(PPh3)3][X] (X 4;= 4;HF2, BF4 or SbF6), have been studied in both wet and dry chlorinated solvents and the only reactions observed have been due to the presence of water, producing, initially, [Pt(OH)(PPh3)3]+ and subsequently the ortho-metallated products [Pt(PPh3)3(C6H4PPh2)][X], which have been characterised by mass spectrometry, multinuclear NMR spectroscopy and, when X 4;= 4;SbF6, by single-crystal X-ray crystallography. |
