The reactivity of AgIIF2 towards forty two inorganic compounds containing oxo- and chloro- ligands, has been investigated. Five families of compounds were studied: (i) binary oxides of metals and nonmetals, (ii) ternary salts of inor

**1**9F NMR has been observed in the antiferromagnetic phases of CuF//2 and AgF//2. These compounds, which are known to have similar magnetic structures, have been shown to have similar magnetization curves and to have saturation sublattice magnetizations

Over 30 years after the first successful syntheses of CuI alkoxides and silyl oxides, the first homologous AgI compounds were synthesized and characterized (see scheme). AgOC(CF3)3 was furthermore found to be a promising precursor for chemical vapor deposition processes and the deposition of AgF (Chemical Equation Presented).

As part of a comprehensive study of square planar palladium(II) and platinum(II) carbonyl derivatives, the molecular structure of cis-Pt(CO)2(SO3F)2, the complete vibrational spectra of cis-Pt(CO)2Cl2, and the attempted synthesis of cis-Pt(CO)2F2 are reported, cis-Pt(CO)2(SO3F)2 is isostructural with cis-Pd(CO)2(SO3F)2 and crystallizes in the monoclinic space, group P21/n (no. 14). Crystal data: a = 7.419(1) A; b = 14.751(2) A; c =8.634(1) A; β = 89.95(1)°; V= 944.9(2) A3; Z = 4; T = 300 K; R [F(o) > 4σ(F(o)) = 0.0447 and wR2 = 0.1097. The internal bond parameters of the cis-Pt(CO)2(SO3F)2 are compared to those of cis-Pd(CO)2(SO3F)2, cis-Pt(CO)2Cl2, and [M(CO)4]2+, M = Pd, Pt. Solid cis-Pt(CO)2Cl2 is studied by IR and Raman spectroscopy, and the data are compared to those of the matrix-isolated complex by IR spectroscopy. Vibrational assignments are supported by DFT calculations, which provide, in addition to vibrational wavenumbers, estimates of IR and Raman band intensities. The positions of 12 of the expected 15 fundamentals of cis-Pt(CO)2Cl2 are obtained experimentally. Attempts to synthesize cis-Pt(CO)2F2, using, in addition to cis-Pt(Co)2X2, X = Cl or SO3F, [Pt(CO)4][Sb2F11]2 or PtF6 as starting material and toluene or anhydrous hydrogen fluoride as the reaction medium, are unsuccessful. There are however two interesting results: The reductive carbonylation of PtF6 in HF produces with [Pt(CO)4][PtF6] the first carbonyl fluoride of platinum, and the reaction of [Pt(CO)4][Sb2F11]2 and CsF in HF results in the formation of the previously reported anionic cluster complex Cs2[Pt3(CO)6](n?10). The inclusion of [M(CO)4]2+, M = Pd, Pt, provides new insights into the nature of the Pd(II)-CO and Pt(II)-CO bonds.

Nitrogen trifluoride (NF3) was used to fluorinate the metallic residue from the dissolution of a high burnup, boiling water reactor fuel (～70 MWd/kgU). The washed residue included the noble-metal phase (containing ruthenium, rhodium, palladium, technetium, and molybdenum), smaller amounts of zirconium, selenium, tellurium, and silver, along with trace quantities of plutonium, uranium, cesium, cobalt, europium, and americium, likely as their oxides. Exposing the noble metal phase to 10% NF3 in argon, between 400 and 550 °C, removed molybdenum and technetium near 400 °C as their volatile fluorides, and ruthenium near 500 °C as its volatile fluoride. The events were thermally and temporally distinct and the conditions specified provide a recipe to separate these transition metals from each other and from the nonvolatile residue. Depletion of the volatile fluorides resulted in substantial exothermicity. Thermal excursion behavior was recorded with the thermal gravimetric instrument operated in a non-adiabatic, isothermal mode; conditions that typically minimize heat release. Physical characterization of the noble-metal phase and its thermal behavior are consistent with high kinetic velocity reactions encouraged by the nanoparticulate phase or perhaps catalytic influences of the mixed platinum metals with nearly pure phase structure. Post-fluorination, only two products were present in the residual nonvolatile fraction. These were identified as a nano-crystalline, metallic palladium cubic phase and a hexagonal rhodium trifluoride (RhF3) phase. The two phases were distinct as the sub-μm crystallites of metallic palladium were in contrast to the RhF3 phase, which grew from the parent, nano-crystalline noble-metal phase during fluorination, to acicular crystals exceeding 20-μm in length.

Technetium pentacarbonyl fluoride [TcF(CO)5] was prepared for the first time by reaction of [TcI(CO)5] with solid AgF in a dichloromethane solution at -23 °C. Low temperature crystallization of the resulting compound in a glass vial yielded an unusual complex [Tc(CO)3(OH)0.49F0.51]4·[Tc(CO)5(BF4)] characterized by single crystal XRD.
