Indexed powder diffraction data for Lu(OH)3 are reported. The compound is cubic, Im3(No. 204), with a = 8.2221(3)Å, V = 555.84Å3, Z = 8, Dm = 5.36(4)Mg m−3 (Dx = 5.40Mg m−3). The refined cell parameter was determined by employing a Siemens Debye-Scherrer camera (Cu radiation, Ni filter). The indexed data were evaluated according to the quantitative figures of merit FN and M20 (F29 = 20(0.028,51) and M20 = 43.5). A thermal gravimetric analysis is presented. The JCPD S Diffraction File No. for Lu(OH)3 is 38–1500.
