Different representations of the tetrel bonds linking the [SnI3]− ion into linear chains in direction of the twofold rotation axis. (above) side-view on a chain as polyhedron model with resulting octa­hedra (left) and constituting trigonal-pyramids (right), all atoms are drawn as thermal displacement ellipsoids at the 60% probability level and the tetrel bonds as dashed sticks, (below, left) geometric parameters [Å,°] characterizing the tetrel bonds with asymmetry parameters Q (grey), and (below, right) space-filling model visualizing the inter-penetration of the van der Waals radii of tin and iodine as result of the tetrel bond formation, inter-penetration indices p (grey), colour code and van der Waals radii as previously.
