In the process of establishing the phase diagram of the Yb/sub 2/O/sub 3/-Fe/sub 2/O/sub 3/-CuO system in air at 1000/sup 0/C, Kimizuka and Takayama prepared a new compound, Yb/sub 2/Cu/sub 2/O/sub 5/, and reported its d-spacings and relative intensities of powder X-ray diffraction. Uhlig and Hahn synthesized the Cu/sub 2/Y/sub 2/O/sub 5/ compound at 1000/sup 0/C in air and reported its crystal data (space group: P/sub 2/, a = 13.60 (angstrom), b = 3.27 (angstrom), c = 13.60 (angstrom), and ..beta.. = 133.15/sup 0/, z = 4, Dx = 5.79). In the present note, we report crystal data of Yb/sub 2/Cu/sub 2/O/sub 5/ and its isostructural compounds, Ln/sub 2/Cu/sub 2/O/sub 5/ (Ln:Lu, Yb, Tm, Ho, Er, Dy, Tb, and Y), and their synthesis conditions.
