The bilayered rhodium oxide (formula presented) was synthesized by high-pressure and high-temperature heating techniques. The single-phase polycrystalline sample of (formula presented) was characterized by measurements of magnetic susceptibility, electrical resistivity, specific heat, and thermopower. The structural characteristics were investigated by powder neutron diffraction study. The rhodium oxide (formula presented) (formula presented) is isostructural to the metamagnetic metal (formula presented) with five (formula presented) electrons per Rh, which is electronically equivalent to the hypothetical bilayered ruthenium oxide, where one electron per Ru is doped into the Ru-327 unit. The present data show the rhodium oxide (formula presented) to be metallic with enhanced paramagnetism, similar to (formula presented) However, neither manifest contributions from spin fluctuations nor any traces of a metamagnetic transition were found within the studied range from 2 K to 390 K below 70 kOe. © 2002 The American Physical Society.
