Abstract
The alkali metal cobalt chalcogenides Na6CoS4, Na6CoSe4, and K6CoS4 cr ystallize in the space group P6(3)mc with Z = 4. The structure is char acterized by isolated [CoX(4)]-tetrahedra. The magnetic susceptibiliti es show Curie-Weiss behaviour. The deviations at low temperatures are caused by antiferromagnetic interactions. The magnetic moments are dis cussed with regard to ligand-field parameters.
