  The electronic spectra of jet-cooled HGeCl and HGeBr

  摘要：

  Laser-induced fluorescence spectra of jet-cooled HGeCl, DGeCl, HGeBr, and DGeBr have been obtained using the pulsed discharge technique. The germylenes were produced by an electric discharge through argon seeded with the appropriate monohalogermane (H3GeX or D3GeX). All three excited state vibrational frequencies have been obtained for each of the four molecules. Analysis of the rotational structure of the 000 bands of the Ã 1A″–X̃ 1A′ band system allowed the determination of r0 structures in the ground and excited states, with the bond angles constrained to previous ab initio values. The results for HGeCl are: r0″(Ge–Cl)=2.171(2) Å, r0″(H–Ge)=1.592(1) Å, θ0″(HGeCl)=94.3°, r0′(Ge–Cl)=2.146(15) Å, r0′(H–Ge)=1.613(2) Å, θ0′(HGeCl)=114.5°; and for HGeBr: r0″(Ge–Br)=2.329(12) Å, r0″(H–Ge)=1.598(6) Å, θ0″(HGeBr)=93.9°, r0′(Ge–Br)=2.308(1) Å, r0′(H–Ge)=1.615(1) Å, and θ0′(HGeBr)=116.3°. The radiative lifetimes of the Ã 1A″ states of HGeCl and HGeBr have been measured to be 548±19 ns and 736±24 ns, respectively.

  Reduction and oxidation potentials of GeI2, GeBr2 . B (B = dioxane, PPh(3)), GeCl2 . B (B = dioxane, PPh(3), AsPh(3), Py, dip), SnCl2 . dioxane, SnX(2) (X = F, Cl Br, I) were measured in MeCN at 20 degrees C. The data obtained indicate that in many cases the EX(2) and EX(2) . B (E = Ge, Sn) can act not only as a good reducing agents, but also as strong oxidants. Examples of redox reactions in which EX(2) and EX(2) . B react as oxidizing agents were found. The variation of the redox potentials of the dihalogermylenes and dihalostannylenes with complexation and with the nature of the halogen substituent and the Lewis base is discussed. In some cases (GeI2, GeX(2) . B; X = Cl, Br, B = dioxane, PPh(3)), the reduction or oxidation was found to be quasi-reversible, indicating the presence of relatively stable ion radicals. AM1 calculations on GeCl2 . dioxane and GeCl2 . PH3 complexes show that the complexation destabilizes both the highest occupied and the lowest unoccupied MOs of the carbene analogues. The complexation reduces the IP and lowers the oxidation potential; its influence on the electron affinity is not straightforward. Calculations of the ion radicals of GeCl2 and GeCl2 . B (B = dioxane, PH3) show that in the ground state an unpaired electron occupies sigma-MO in the cation and pi-MO in anion radicals.
