Received: 1 June 2011; in revised form: 14 June 2011 / Accepted: 21 June 2011 / Published: 27 June 2011 Abstract: Single crystals of ternary chalcogenides with the composition BaLu Ch (Ch = 2 4 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 BaN Cl as a nitrogen 3 source. Their crystal structures are isotypic with CaFe2O4 containing two sorts of 1 {[LuCh e Ch t ]8–} chains built up of edge-linked [(Lu1)(Ch2)(Ch3) (Ch4) ]9– and
