Magnetic susceptibility of 1 as a function of temperature. The magnetic susceptibility data have been measured in an applied magnetic field of H = 0.1 T over the temperature range T = 2-300 K. The data is plotted as χ _M T vs. T and shows characteristic antiferromagnetic behavior. The inset shows the 1/χ _M vs. T data; the solid line is a fit of the experimental data to the Curie–Weiss law.
