Twofold superstructure of TiOBr at T = 17.5 K
What is it about?
The low-temperature structure of titanium(III) oxybromide is reported as a twofold superstructure of the crystal structure at room temperature. Structure refinements and analysis were carried out within the higher-dimensional superspace approach.
Why is it important?
Both the low-temperature and the room-temperature structures of TiOBr are isostructural with the corresponding structures of TiOCl. The results indicate that at low temperatures TiOBr is in a spin-Peierls state, similar to that of TiOCl, but with the modulations and relevant interactions smaller than in the latter compound.
