Neutron diffraction for a polycrystalline sample ofLaCo$_{0.8}$Rh$_{0.2}$O$_{3}$ and synchrotron x-ray diffraction forpolycrystalline samples of LaCo$_{0.9}$Rh$_{0.1}$O$_{3}$ andLaCo$_{0.8}$Rh$_{0.2}$O$_{3}$ have been carried out in order to investigate thestructural properties related with the spin state of Co$^{3+}$ ions. We havefound that the values of the Co(Rh)-O bond lengths in the Co(Rh)O$_{6}$octahedron of LaCo$_{0.8}$Rh$_{0.2}$O$_{3}$ are nearly identical at 10 K. Thelattice volume for the Rh$^{3+}$ substituted samples decreases with the thermalexpansion coefficient similar to that of LaCoO$_{3}$ from room temperature, andceases to decrease around 70 K. These experimental results favor a mixed stateconsisting of the high-spin-state and low-spin-state Co$^{3+}$ ions, andsuggest that the high-spin-state Co$^{3+}$ ions are thermally excited inaddition to those pinned by the substituted Rh$^{3+}$ ions.
