Projection of the crystal structure of Na4[UO2(CO3)3] onto the 100 plane. Note the chain of alternating octahedra around the Na1 and Na2 atoms parallel to [001] at the unit-cell edge. Colour-coding of polyhedra, red: UO2O6 polyhedron; blue: planar CO3 triangles; yellow: NaO6 octahedra; green: NaO5 irregular square pyramid. |
