Neptunium(III) copper(I) diselenide

The title compound, NpCuSe2, is the first ternary neptunium transition-metal chalcogenide. It was synthesized from the elements at 873 K in an evacuated fused-silica tube. Single crystals were grown by vapor transport with I2. NpCuSe2 crystallizes in the LaCuS2 structure type and can b...
