    • The interslab translation in species 2 is 12.84 Å(c/3, Nevertheless, to draw a more realistic picture of the [DAMS, cations packing within the slabs, the van der Waals radii of the atoms reasonably involved in the layer-[DAMS+]⋯layer interactions must be taken into consideration. Considering the negative charges mainly localized on the iodine atoms and the positive ones on the methylated heterocyclic nitrogen atoms, I(δ-)⋯(δ+)H-C-N-C- H(δ+)⋯(δ-)I interactions would develop between adjacent layers. The shortest I-I interlayer distance is 8.79 Å(Figure 4, while the expected length of the I(δ, ⋯(δ+)H-C-N-C-H(δ+)⋯(δ -)I moiety is ca. 10.3 Å. This would imply some tilting of the [DAMS, cations with respect to the c axis; however, it must be pointed out tha
    • -)I interactions possess a certain degree of electrostactic character, so distances computed from van der Waals radii are somewhat overestimated.

    • Alternatively, the consecutive guest layers could be iso-oriented (leading to a macroscopic polarity lying in the ab plane, We do not have any direct evidence to discriminate between the two hypotheses; however, the presence of equally oriented guest layers should promote some (yet unobserved) distortion of the rhombohedral host lattice.
