Abstract

Gas-phase electron diffraction (GED) studies at high temperatures have several special common features that justify their separate discussion. Due to the difficulties connected with the experiment this technique has developed only in a few laboratories. Most often inorganic systems are studied; lower-valence metal halides and metal oxides. Their low volatility requires high-temperature experimental conditions. Due to the complex vapor composition, other techniques, such as quadrupole mass spectrometry and, to an increasing degree, quantum chemical calculations accompany these GED studies. The analyses often reveal unanticipated structures. In this paper some unexpected and interesting structures of metal halide dimers will be shown, some from GED, others from computations carried out in connection with the high-temperature GED studies of metal halide systems of low volatility.
