Effect of delithiation on the dimer transition of the honeycomb-lattice ruthenate Li${}_{2-x}$RuO${}_3$

Abstract

The honeycomb-lattice ruthenate Li${}_2$RuO${}_3$ is made heavily Li-deficient by chemical oxidation by iodine. The delithiation triggers a different phase Li${}_{2-x}$RuO${}_3$, the "D-phase", with superlattice. For the first time we disclose the magnetic and structural properties of the D-phase in the dimer-solid state. The low temperature magnetic susceptibility and the bond lengths indicate a bonding configuration consisting of both Ru${}^{4+}$-Ru${}^{4+}$ and Ru${}^{5+}$-Ru${}^{5+}$ dimers.
