Platinum compounds heteronuclear

The 31P H NMR spectra of a number of heteronuclear gold cluster compounds are found to be deceptively simple and NMR studies have been used as a probe of the behavior of these species in solution. This is especially true of the higher nuclearity clusters, which often exhibit spectra that are much simpler than would be predicted on the basis of their solid-state structures. For example, [Pt(H)(PPh3)(AuPPh3)7]2+, which adopts the solid-state structure illustrated in Fig. 9 (137) in which the phosphine ligands occupy several different chemical environments within the molecule, shows only two resonances in the 31P 1H NMR spectrum. These are in a ratio of 7 1 and exhibit satellites due to coupling to the central platinum nucleus as Fig. 10 illustrates. [Pg.345]

Alkyne complexes of platinum have also been prepared from 3,3,3-trifluoropropyne, and parameters for compounds [293] to [295] are given in Table XVII. (151) Parameters for the silylacetylene complex rra/ii-Pt(PEt3)2(Cl)(SiH2C]CCF3), 5—51-3 for the terminal CF3 group, with 5/(Pt-F) +23-7 Hz and 5/(F-H) 2-2 Hz, were obtained by heteronuclear double resonance.
