Popis:	The not new phases LiCuFeSe2 and NaCuFeSe2 were prepared from the corresponding carbonates and CuFeSe2. They crystallize as the isostructural sulphide phases LiCuFeS2 and NaCuFeS2 in the trigonal space group P 3 m1 (No. 164) in a layered Li2FeS2 structure type. The Se atoms form an h.c.p. array, the copper and iron atoms are statistically distributed in the tetrahedral sites whereas the alkali metals are placed in the octahedral sites in the van der Waals gap.
