The compound Cs2U3Se7 has been synthesized at 1273 K by the reaction of U, Se, As, and Cs2Se3. The compound crystallizes in a new structure type in the orthorhombic space group D2h16-Pnma with four formula units in a cell of dimensions a = 22.847(1) Å, b = 4.172(1) Å, c = 16.639(1) Å. In the asymmetric unit there are three independent U atoms, each octahedrally coordinated by six Se atoms. These USe6 octahedra are connected to form a channel structure with the channels running in the [010] direction. Within the unit cell the channel comprises twelve U centers.
