Sumario:The title compound, NpCuSe(2), 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 I(2). NpCuSe(2) crystallizes in the LaCuS(2) structure type and can be viewed as a stacking of layers of CuSe(4) tetra­hedra and of double layers of NpSe(7) monocapped trigonal prisms along [100]. Because there are no Se—Se bonds in the structure, the formal oxidation states of Np/Cu/Se may be assigned as +III/+I/−II, respectively.
