Figure 5
The relative occupancies of M atoms around the ring positions are illustrated by spheres with occupancies used as the radius. The numbering of metal positions runs clockwise with position 1 at the top. The displacement ellipsoids at the F atoms signify 90% probability density. Left, Cr7Fe; centre, Cr7Co; right, Cr7Ni. Colour code: white H, light blue N, lime green F, red Fe, dark licac Co, and green Ni atoms. |
