“…Lanthanum and cerium halothiosilicates are isostructural with the homologous halooxosilicates (27). In the latter family, the Ce''' emission lies in the ultraviolet, whereas, in the former, because of the covalency of the cerium}chalco-gen bonding, the emission is displaced into the visible.…”

“…Apart from samarium, europium, and gadolinium fluoride borates, lanthanum, cerium, praseodymium, and neodymium chloride silicates along with lanthanum and cerium bromide silicates [30] also crystallize in this structure type with the space group С2/с. Note that in fluoride borates Ln 3 (BO 3 ) 2-x F 3+3x (Ln 3+ = Sm 3+ , Eu 3+ , Gd 3+ ) as well as in the M 7 (BO 3 ) 3 [X 4 ]Z structure type (see above), the F -anions are subdivided into "isolated" (Z -) and "grouped" (in the composition of the [X 4 ] 4-anionic groups).…”

In the work the structures of fluoride borates demonstrating the substitution with the stoichiometry (BO 3 ) 3-↔ 3F -are analyzed and the specific role of tetrahedral anionic [X 4 ] 4-groups is revealed in this substitution. The possibility of the F-F interaction in [F 4 ] 4-groups uncharacteristic of ionic crystals is confirmed by ab initio quantum chemical simulation of the crystal structure of Ba 4-x Sr 3+x (BO 3 ) 4-y F 2+3y .

Inhaltsübersicht. Einkristalle der BromidϪThiosilicate Ln 3 Br[SiS 4 ] 2 wurden durch Reaktion von Lanthanidmetall (Ln ϭ La, Ce, Pr, Nd, Sm, Gd), Schwefel, Silicium und elementarem Brom in Quarzglasampullen dargestellt. Die Thiosilicate kristallisieren monoklin in der Raumgruppe C2/c (Z ϭ 4) isotyp zu den IodidϪAnaloga Synthesis and Crystal Structures of Lanthanide Bromide Thiosilicates Ln 3 Br[SiS 4 ] 2 Abstract. Single crystals of the bromideϪthiosilicates Ln 3 Br[SiS 4 ] 2 were prepared by reaction of lanthanide metal (Ln ϭ La, Ce, Pr, Nd, Sm, Gd), sulfur, silicon and bromine in quartz glass tubes. The thiosilicates crystallize in the monoclinic spacegroup C2/c (Z ϭ 4) isotypically to the iodide analogues Ln 3 I[SiS 4 ] 2 and the AϪtype chlorideϪoxosilicates Ln 3 Cl[SiO 4 ] 2 with the following lattice constants: La 3 Br[SiS 4 ] 2 : a ϭ 1583.3(4) pm, b ϭ 783.0(1) pm, c ϭ 1098.2(3) pm, β ϭ 97.33(3)°C e 3 Br[SiS 4 ] 2 : a ϭ 1570.4(3) pm, b ϭ 776.5(2) pm, c ϭ 1092.2(2) pm, β ϭ 97.28(2)°P r 3 Br[SiS 4 ] 2 : a ϭ 1562.6(3) pm, b ϭ 770.1(2) pm, c ϭ 1088.9(2) pm, β ϭ 97.50(2)°E
