a Thermal dependence of magnetic susceptibility in the temperature range 2–300 K of dg-MUV-29. The experimental data (expt., black line) have been fitted (red dotted line) following the Curie-Weiss model. b Temperature dependence of the a.c. susceptibility of dg-MUV-29 measured at different frequencies. c Mössbauer measurements at different temperatures of dg-MUV-29. The lines over the experimental points are the estimated distributions of quadrupole splittings (QS). d I(Q) data, offset by 5000; dots represent the experimental data of dg-MUV-29, and the line represents the Monte Carlo (MC) simulation. The MC simulation is matched to temperature, with 1.8 K data plotted against 13 K. An empirical scale, offset, and linear background have been applied to all MC data, fixed to the lowest temperature, and distances are scaled by the experimentally determined metal-metal distance r0 = 6.20 Å. e Real space spin correlation function derived from MC simulations showing antiferromagnetic alternation that decays with increasing distance, r Source data are provided as a Source Data file.
