Abstract
CS2Au2I6 is a halogen bridged three-dimensional mixed valence Au compl ex. This complex undergoes a semicondUCtor-to-metal transition and a m etal-to-metal transition under high pressures. The second metallic pha se appearing at P greater-than-or-similar-to 6,5 GPa and T greater-tha n-or-similar-to 60-degrees-C has a cubic perovskite structure and can be obtained as a metastable state at room temperature and ambient pres sure. From an interest in the electronic state of the cubic phase in C s2Au2I6, we investigated the Au-197 Mossbauer spectrum for the metasta ble cubic phase in Cs2Au2I6.
