“…81 As mentioned above, an unusual thing about these compounds is that number of ligands per metal cation is quite large (recollect, both XeF 2 and MF 6 2 may still act as bridging ligands to more then one metal center!). The total number of ligands may be as large as 3 per Ag I , Li I 86 PtNg, PtNg 2 and PdNg 2 , 87 XeM(CO) (M = Ni, Co), and XeM(N 2 ) (M = Ni), 88 NgMO (M = Cr … Ni, Ng = Ar … Xe), 89 organometallic complexes of Re and Xe, 90 and XeTi 2 , 91 have also been considered in this figure. Affinity of XeF 2 to act as a ligand towards 'naked' metal cations has been summarized in Fig.…”
