Figure 3
View down [001] of a slice (0.25 ≤ z ≤ 0.35) of the structure of (I). Displacement ellipsoids are displayed at the 50% probability level. [Symmetry codes: (iii) 1 − x, 1 − y, 1 − z; (iv) − y, x, z; (v) − y, x, z; (vi) + y, 1 − x, 1 − z; (vii) + x, + y, 1 − z.] Note that Cl1 and Cl2 lie on fourfold axes and Cl3 lies on a twofold axis. The chloride ions link to the sodium and potassium ions shown in Figs. 1 and 2 to generate infinite stacks of alternating NaO4Cl2 and KO4Cl2 octahedra. |
