γ‐HIO 3 – a Metastable, Centrosymmetric Polymorph of Iodic Acid
Abstract From solutions of chromium(III) perchlorate and periodic acid, single crystals of γ‐HIO 3 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...

| Summary: | Abstract
From solutions of chromium(III) perchlorate and periodic acid, single crystals of γ‐HIO
3
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 (HIO
3
)
2
, which are formed by hydrogen bonds. The crystals are metastable and transform into the stable modification, α‐HIO
3
, within a couple of weeks. |
