The decomposition of Gd 2 (SeO 4 ) 3 in the presence of LiF in sealed gold ampoules yields single crystals of Gd 3 (SeO 3 ) 4 F (hexagonal, P6 3 mc, Z = 2, a = 1044.3(1), b = 694.32(7) pm, R all = 0.0286). In the crystal structure one SeO 3 2± group and one F ± ion cap a ring of three Gd atoms. Fur
