Structural effects on the magnetic properties of ferric complexes in molecular materials or a lamellar CdPS3 host matrixElectronic supplementary information (ESI) available: Table S1 lists the least-squares planes (x, y, z in crystal coordinates) and deviations from them. Figure S1 shows the powder X-ray diffraction patterns recorded at room temperature for the CdPS3 phase, the pre-intercalate with the NMe4+ cation and the intercalated materials 9 and 10. Figures S2 and S3 display the room temperature IR spectra of 9 and 10, which are compared to those of 1 and 5, respectively. Figures S4 and S5 show the EPR spectra of 8 (293 K) and 10 (5 and 291 K).
