Abstract: | Gd3(SeO3)4F: A Fluoride Selenite with μ3‐SeO32– and μ3‐F– Capped Gd3 Rings The decomposition of Gd2(SeO4)3 in the presence of LiF in sealed gold ampoules yields single crystals of Gd3(SeO3)4F (hexagonal, P63mc, Z = 2, a = 1044.3(1), b = 694.32(7) pm, Rall = 0.0286). In the crystal structure one SeO32– group and one F– ion cap a ring of three Gd atoms. Furthermore, the crystal structure is strongly influenced by the lone pairs of the SeO32– ions. |
