The compounds Ln{sub 2}Ba{sub 2}O{sub 5}, Ln{sub 2}Ba{sub 4}O{sub 7}, and Ln{sub 4}Ba{sub 3}O{sub 9}, for Ln = Dy, Ho, Er, Tm, and Yb, have been prepared and characterized by X-ray powder diffraction. Phase interrelationships were established as a function of temperature by quenching specimens annealed at 900-l 100{degree}C. Comparable Ln = Tb phases could not be prepared. Lattice parameters are presented for all phases observed.
