Abstract
A tetradentate host system with four C![[triple bond, length as m-dash]](https://www.rsc.org/images/entities/char_e002.gif)
C–Sb(C2F5)2 functions binds halide ions in a distorted square planar coordination. Experimental and calculated structures reveal a complex interplay of attractive pnictogen bonding and Coulomb repulsion.

Abstract
The filled skutterudite KRu4Z12 (Z = As12, Sb12) crystallizes in the unique BCC structure with space group Im![[3 with combining macron]](https://www.rsc.org/images/entities/char_0033_0304.gif)
and contains 17 atoms per unit cell. The K atom takes the atomic position of (0 0 0), Ru atoms are positioned at (0.25 0.25 0.25), and Sb & As atoms are located at (0, 0.35, 0.16).
