Abstract: Single crystals of ternary chalcogenides with the composition BaLu2Ch4 (Ch = S, Se and Te; orthorhombic, Pnma; a = 1211.4–1353.6, b = 395.6–438.5, c = 1427.8–1593.6 pm) could be obtained after attempts to synthesize ternary lutetium(III) nitride chalcogenides using the elements (Lu and Ch) along with BaN3Cl as a nitrogen source. Their crystal structures are isotypic with CaFe2O4 containing two sorts of {[LuChCh]8–} chains built up of edge-linked [(Lu1)(Ch2)(Ch3)3(Ch4)2]9– and [(Lu2)(Ch1)3(Ch2)2(Ch4)]9– octahedra, respectively. A further interconnection via the chalcogenide anions (Ch3)2– and (Ch1)2– leads to double chains, where either (Lu1)3+ or (Lu2)3+ coordinates these chalcogenide anions as well. The three-dimensional framework {[Lu2Ch4]2–} emerges from the corner-linkage of the two kinds of double chains forming large channels apt to take up the Ba2+ cations. These divalent cations exhibit eight contacts to chalcogenide anions resulting in the formation of bicapped trigonal prisms [BaCh8]14–.
