Abstract: | A high pressure phase BaI2-II, which can be quenched and retained as a metastable form at ambient conditions, is reported. The structure has been determined by X-ray investigations using single crystals. BaI2-II crystallizes in an anti-Fe2P-type arrangement, space group Å, c = 5.173(3)Å, which is slightly denser than the PbCl2-type structure found at normal pressure. Structural features of the two phases are discussed in comparison. |
