An X-ray diffraction pattern for ErNi2Ge2 at room temperature is reported.
ErNi2Ge2 is tetragonal with lattice parameters a = 4.0191(2) Angstrom, c =
9.7643(2) Angstrom, space group I4/mmm, and Z = 2. The lattice parameters d
erived from Rietveld analysis agree well with the results of a least-square
s refinement. (C) 1999 International Centre for Diffraction Data. [S0885-71
