ヘリウムを圧力媒体とした高圧単結晶構造解析

抄録

In this paper, a technique of single-crystal X-ray diffraction measurements under high pressures, using a diamond anvil cell with helium gas as an inert and hydrostatic pressuretransmitting medium, is described. The technique has been applied to a three-dimensional halogen-bridged mixed-valence gold complex, CS₂ [Au^ICl₂] [Au^IIICl₄] to investigate the mixedvalence state and the crystal structure under high pressures up to 18 GPa.
