and periodic acid, single crystals of gamma-HIO3 were obtained and characterized by single-crystal X-ray diffraction, Raman spectroscopy and thermal analysis. The compound crystallizes in the orthorhombic crystal system, space group Pbca (a = 563.92, b = 611.10, c = 1507.16 pm). The structure is built up by dimers (HIO3)(2), which are formed by hydrogen bonds. The crystals are metastable and transform
从高氯酸铬 (III) 和高碘酸溶液中,获得单晶 γ-HIO3,并通过单晶 X 射线衍射、拉曼光谱和热分析表征。该化合物在正交晶系中结晶,空间群 Pbca (a = 563.92, b = 611.10, c = 1507.16 pm)。该结构由二聚体 (HIO3) (2) 构成,二聚体由氢键形成。晶体是亚稳态的,并在几周内转变为稳定的变体 alpha-HIO3。
