Although the product is not strictly a coordination compound of xenon, PtFs reacts with xenon in the presence of fluorine at 200 C to give pteF5] [PtF6] . Xenon is oxidized by PtFs to give both Xe(PtF6) and Xe(PtF6)2. The former compound resembles 02(PtFfi). Similar... 

The powerful technique of X-ray diffraction cannot be applied to the resolution of this question since solid XeF polymerizes with a completely different structure (see below). However, the isoelectronic compound Xe(OTeF )6 crystallizes as a simple molecular solid, so that il may be studied by X-ray diffraction. Each molecule has C l symmetry (for the oxygen coordination shell about the xenon) indicating a stereo-chemically active lone par (Fig. 6.13.0. suggesting the same structure in XeF us well.n... 

Laboratory in Oxford, and Geoffrey Ozin at the University of Toronto in the early 1970s. With the metal atom cocondensation technique (which as described in Chaps. 6 and 7 was also used to prepare a series of zerovalent arene and olefin metal complexes), they reported simultaneously that the elusive palladium and platinum tetracarbonyls, Pd(CO)4 and Pt(CO)4, as well as the coordinatively unsaturated fragments M(CO)3, M(CO)2, and M(CO) (M = Pd, Pt) were formed by cocondensation reactions of Pd and Pt atoms with CO in inert gas matrices at 4-10 K [119-122]. The comparison of the CO bond stretching force constants for Pd(CO)ra and Pt(CO)ra (n - 1-4) revealed that, in analogy to Ni(CO) , the most stable compounds were the tetracarbonyls. In a xenon matrix, Pd(CO)4 existed up to about 80 K [120]. Ozin s group as well as others...
