Structure of the novel sodium sesquichloride tP10-Na₂Cl₃ synthesized in this work. (a) Unit cell viewed along the c direction; Na atoms are red, and Cl atoms are blue; (b) Na–Cl1 nets and Cl2 nets, which alternate in the c direction (Na and Cl2 form the 2D tiling of the same 3².4.3.4 topology); and (c) polyhedral model of the structure; the Na coordination polyhedron is shown separately.
