Temperature-dependent magnetic properties for (2S,5S)-8NO8₂. a χ_para–T plot and b χ_paraT–T plot in a magnetic field of 0.05 T. The circles denote the experimental data in the first heating process, the solid lines denote the Curie–Weiss curve with C = 0.398 emu K mol⁻¹ and θ = −0.032 K fitted between 313 and 327 K. Temperature dependence of c χ_rel, d g-value, e ∆B_pp^L, and f ∆B_pp^G for (2S,5S)-8NO8₂ obtained by EPR spectroscopy in a magnetic field of 0.33 T in the first heating process. Vertical dashed lines denote the Cr-to-SmC* and SmC*-to-Iso phase transition temperatures determined from the peaks in the DSC charts and g-value changes
