    Notes: The reaction of trimethylarsane in the superacidic systems hydrogen/fluoride antimony pentafluoride and hydrogen fluoride/arsenic pentafluoride leads to trimethylarsonium fluorometallates. These salts are stable up to 60 °C and 5 °C, respectively. Structures were successfully elucidated in the cases of trimethylarsonium undecafluorodiarsenate and trimethylarsonium hexafluoroantimonate. (CH3)3AsH+As2F11- crystallizes in the monoclinic space group P21/n with four formula units per unit cell with the dimensions a = 7.362(1), b = 12.589(1), c = 13.598(1) Å and β = 95.37(1)°. (CH3)3AsH+SbF6- crystallizes in the monoclinic space group P21/m with four formula units per unit cell with the dimensions a = 8.313(1), b = 8.855(1), c = 13.285(1) Å and β = 94.358(1)°.

    Notes: The electronic structure of the title compound 1 has been investigated by UV photoelectron spectroscopy and quantum chemical calculations. 1 has two nearly degenerate nN lone-pair orbitals which form the two highest occupied MOs. The third highest occupied MO is mainly localized at the oxygen atom (n0). All calculations indicate that the molecule has a twisted C2 conformation.

    Notes: The molecular structure of (CF3)2NOCH3 was determined by gas electron diffraction. The molecular intensities were reproduced by use of a single conformation with syn orientation of the O-CH3 group relative to the nitrogen lone pair. This was confirmed by ab initio calculations (HF/3-21G(*), polarization functions only on nitrogen, and MP2/6-31G*). The observed structure demonstrates that the generalized anomeric effect is of minor importance to this compound. The following skeletal geometric parameters (bond lengths [pm] and angles [°] with 3-s̰ uncertainties) were derived: N-C 142.9(7), N-O 142(3), O-C 145(3), CNC 118.0(9), CNO 108.1(17), and NOC 109.4(17). The experimental structure is well reproduced by the ab initio calculations.
