Abstract

Here, the photochemical behavior of [Tc₂Cl₈]^2– was investigated in acetonitrile. The speciation of Tc before and after irradiation at 254 nm was performed by UV-visible spectroscopy and electrospray ionization mass spectrometry (ESI-MS). Upon irradiation at 254 nm, [Tc₂Cl₈]^2– was unstable, the scission of the Tc ≡ Tc unit occurred and the complex [TcCl₄(CH₃CN)₂] was identified. The disappearance rate of [M₂Cl₈]^2– (M = Tc, Re) under irradiation has been measured and was ~7.5 time faster for Tc than for Re.

Metal-metal multiply-bonded complexes of technetium. 2. Preparation and characterization of the fully solvated ditechnetium cation [Tc{sub 2}(CH{sub 3}CN){sub 10}]{sup 4+}

Journal Article Bryan, J C ; Cotton, A ; Daniels, L M - Inorganic Chemistry

Acidification of Tc{sub 2}Cl{sub 4}(PR{sub 3}){sub 4} with HBF{sub 4}{center_dot}Et{sub 2}O in a mixture of acetonitrile and methylene chloride results in the formation of the metal-metal triply-bonded solvated complex [Tc{sub 2}(CH{sub 3}CN){sub 10}][BF{sub 4}]{sub 4} (1) in 80% yield. This compound may also be prepared through reduction of [Bu{sub 4}N]{sub 2}[TcCl{sub 6}] with either Bu{sub 3}SnH or finely divided Zn followed by treatment with HBF{sub 4}{center_dot}Et{sub 2}O, but in lower yields (approximately 50%). The quadruply bonded species Tc{sub 2}Cl{sub 8}{sup 2{minus}} also reacts with HBF{sub 4}{center_dot}Et{sub 2}O in a mixture of acetonitrile and diethyl ether under mild heating to producemore »« less

Technetium-carbon multiple bonds. Synthesis and structure of Tc(=C=CHPh)Cl(dppe)[sub 2] and [Tc([triple bond]C-CH[sub 2]-t-Bu)Cl(dppe)[sub 2]][sup +]

Journal Article Burrell, A K ; Bryan, J C ; Kubas, G J - Organometallics; (United States)

The 16-electron complex TcCl(dppe)[sub 2] reacts with terminal alkynes to form neutral vinylidene complexes of the type Tc(=C=CHR)Cl(dppe)[sub 2] (R = Ph, Me, t-Bu). Treatment of these vinylidene complexes with acid (HBF[sub 4] for R = Ph, HNMe[sub 3]BPh[sub 4] for R = t-Bu) yields the respective terminal carbyne complexes Tc([triple bond]CCH[sub 2]R)-Cl(dppe)[sub 2][sup +] (R = Ph, t-Bu). These vinylidene and carbyne compounds represent the first examples of technetium carbenes or carbynes. X-ray structures of Tc(=C=CHPh)Cl(ddpe)[sub 2] and Tc([triple bond]CCH[sub 2]-t-Bu)Cl(dppe)[sub 2[minus]+] were determined, and the Tc-C bond lengths obtained were 1.861(9) and 1.724(7) A, respectively. 13 refs., 2more » figs.« less

Journal Article Libson, K ; Doyle, M N ; Thomas, R W ; ... - Inorg. Chem.; (United States)

The components of a reversible Tc(III/II) redox couple have been characterized by single-crystal x-ray analysis and the crystal parameters are reported. Oxidation of the Tc(II) complex to the Tc(III) form causes a shortening of the Tc-Cl bond by 0.105 (2) /angstrom/, consistent with the ionic nature of this interaction. Conversely, oxidation from Tc(II) to Tc(III) causes a lengthening of the Tc-P bond by 0.072 (2) /angstrom/, consistent with the domination of this interaction by ..pi..-back-bonding from Tc to P. The magnitudes of these bond length changes are used to predict the inner-sphere reorganization barrier to electron transfer of the trans-Tc(DPPE)/submore »« less

Journal Article Cotton, F A ; Haefner, S C ; Los Alamos National Lab., NM ; ... - Journal of the American Chemical Society

Efficient (i.e., essentially quantitative) photolysis of multiple bonds, including metal-metal multiple bonds, neither is to be generally expected nor has been observed, with the sole exception of photocleavage of the quadruple bond in [Re{sub 2}Cl{sub 8}]{sup 2-}, which occurs in acetonitrile and affords ReCl{sub 3}(CH{sub 3}CN){sub 3} as the final product. We report here a striking example of such a process, wherein the [(CH{sub 3}CN){sub 5}Tc=Tc(CH{sub 3}CN){sub 5}]{sup 4+} ion is photolyzed in CH{sub 3}CN to give two [Tc(CH{sub 3}CN){sub 6}]{sup 2+} ions in nearly quantitative isolated yield. A plausible idea (admittedly not yet supported experimentally) is that photoexcitation producesmore »« less

Photochemical reactivity of the cluster Mo sub 6 Cl sub 14 sup 2 minus : Photosubstitution and photoredox processes

Journal Article Kraut, B ; Ferraudi, G - Inorganic Chemistry; (USA)

Photoreversible ligand substitution and ligand oxidation reactions have been observed in uv photolyses of Mo{sub 6}Cl{sub 14}{sup 2{minus}} in acetonitrile. The photosubstitution of the ligand detected in {lambda}{sub excit} > 300 nm takes place in competition with population of the low-lying states associated with Mo{sub 6}Cl{sub 14}{sup 2{minus}} phosphorescence and leads to the formation of intermediates that can be scavenged by excess cluster, Br{sup {minus}}, or I{sup {minus}}. The photoredox reaction, investigated by continuous and flash photolyses, has been detected for irradiation at wavelengths of the high energy charge transfer bands, {lambda}{sub excit} < 300 nm.
