Abstract

The compound La24Ru11 (tetracosalanthanum undecaruthenium) crystallizes in a Ce₂₄Co11-type structure. The non-centrosymmetric crystal structure (space group P63 mc) contains RuLa6 trigonal prisms, La6 octahedra and LaRu4 tetrahedra and is closely related to that of Ce23Ni7Mg4. This communication highlights the crystal-chemical similarities and points out the differences between the two structures. All of the tested crystals were inversion twins.
