La/sub 3/WO/sub 6/GAMMAl/sub 3/ is representative of a group of rare earth chlorotungstates, where Ln can also be Ce, Pr, Nd, Sm, Eu, and Gd. The structure was determined and refined to an R value of 3.5%. The space group is P6/sub 3//m with La in 10-coordination and W in an unusual trigonally prismatic 6-coordination. The local site symmetry for W is D/sub 3h./ Powder diffraction data are reported for La/sub 3/WO/sub 6/Cl/sub 3/. Diffuse reflectance, ir, Raman, and luminescence spectra are reported for pure La/sub 3/WO/sub 6/Cl/sub 3/, as well as for the activators Sm, Eu, Tb, Dy, and Tm incorporated into this host.
