Pawley fits of synchrotron XRPD data collected for the HI complexes with m-cresol (a) and m-nitro­phenol (b) on ID22 at ESRF [λ = 1.30079 (2) Å, room temperature]. For both plots, the upper panels show the experimental data (black), calculated pattern (red) and difference profile (blue), with green vertical bars marking Bragg reflections corresponding to the rhombohedral space group R3 of each complex. The data were scaled by factors of 5 and 30 to emphasize the enhanced d-spacing resolution. The lower panels magnify the 2θ range from 1.6° to 4.5°, highlighting angular resolution with the background intensity subtracted for clarity. (a) HI–m-cresol complex with lattice parameters a = 79.7753 (1), c = 40.6005 (2) Å, with goodness of fit χ2 = 1.33 and Rwp = 5.97%. (b) HI–m-nitro­phenol complex with lattice parameters a = 79.8633 (3), c = 40.2489 (1) Å, with goodness of fit χ2 = 1.40 and Rwp = 7.51%.
