Figure 1
An ORTEP-3 (Farrugia, 1997) representation (50% probability displacement ellipsoids) of the asymmetric unit of (II), showing the coordination geometry around the K atoms. Further residues are included to complete the coordination spheres but are simplified for clarity. [Symmetry codes: (i) 1 − x, 2 − y, 1 − z; (ii) 1 − x, 1 − y, 1 − z; (iii) 1 − x, + y, − z; (iv) 1 − x, y − , − z. |
