About Trihalides with TiI3 Chain Structure: Proof of Pair Forming of Cations in
β-RuCl3 and RuBr3 by Temperature Dependent Single Crystal X-Ray Analyses.
— Single crystal X-ray studies of β-RuCl3 and RuBr3 at different temperatures show
that both compounds are dimorphic and show reversible phase transitions at 206 and
384 K, respectively. In the high-temp. forms the Aristo-type of the hexagonal
TiI3-structure with space group P63/mcm (Z = 2) is found. The low-temp. modifications
have the RuBr3-type structure, an orthorhombically distorted variant with space group
Pmmn (Z = 4). — (HILLEBRECHT, H.; LUDWIG, T.; THIELE*, G.; Z. Anorg. Allg.
