New layered chromium chalcogenides CsLiCrSe, RbLiCrS and CsLiCrS: structures and properties.

We report the synthesis, crystal structures and physical properties of three quaternary compounds CsLiCrSe2, RbLiCrS2 and CsLiCrS2, which represent the first discovered ThCr2Si2-type chromium chalcogenides. They all share the same structure with the space group I4/mmm and Cr/Li mixed occupancy without ordering. Specifically, the Cr/Li-S bond length in RbLiCrS2 is found to be close to the low limit of known Cr-S bonds, and so only alkali metals Cs and Rb that are large enough in size can achieve lattice match and form these chromium compounds.
