Abstract

The layered RuBr3-RuI3 honeycomb system was synthesized at high-pressures. The crystal structures are centrosymmetric (space group R-3), and based on honeycomb layers of Ru $^{3+}$ (S=1/2). Their basic physical properties are surveyed. The solid solution switches from insulating to metallic in the range of concentrations between RuBr $_{0.75}$ I $_{2.25}$ and RuBr $_{0.50}$ I $_{2.50}$ . A preliminary structure/property phase diagram is presented. Our results suggest that this solid solution may provide insight into the influence of disorder on spin-orbit-coupled quantum spin liquids.
