Fig. 6: The crystal structure of α-RuCl3 determined by analyzing the Bragg scattering as well as the diffuse scattering of high-quality single crystals at 0.0 GPa and 1.26 GPa.
From: Pressure-tuning of α-RuCl3 towards a quantum spin liquid
The local Cl-Ru-Cl layer geometry is depicted in (a), (c), and two successive honeycomb layers viewed normal to the stacking direction are shown in (b), (d) for the monoclinic C2/m structure at 0.0 GPa and the high-symmetry structure with p\(\bar{3}\)1m layer symmetry at 1.26 GPa, respectively. Equivalent nearest neighbor Ru-Ru links and Ru-Cl bond distances are encoded in the same colors in (a) and (b). For improved clarity, only the two nearest neighbor edge-sharing RuCl6 octahedra are shown in (a).
