Fig. S5 Atomic density profiles of the SrPhP-12C4, SrPhP-12C5, and SrPhP-12C6 intercalates in the direction perpendicular to the host layers. The peaks in atomic density profiles are not labelled mostly due to a high degree of disorder in the interlayer space and the impossibility to assign the peaks to individual atoms.
