Abstract

The reaction of Eu with molten lithium polyselenide produced a new rare-earth dichalcogenide, EuSe2. This compound cannot be obtained via direct combination of the elements and is therefore an example of how alkali metal chalcogenide fluxes can access metastable or kinetically stable phases. The crystals of EuSe2 are very dark red and air stable for several months. The structure was determined with single-crystal X-ray diffraction. The compound crystallizes in the tetragonal space group, I4/mcm (#140) with a = 6.391(1) Å and c = 7.848-.
