The temperature dependence of the magnetisation per copper m Cu in units of µ B and the corresponding magnetic susceptibility χ in emu mol -1 Oe -1 for a single crystal of the coordination polymer measured at 1 T are plotted in the temperature range 2-300 K in Figure . The single crystal was placed horizontally inside a gelatin capsule so that the crystal's major axis is perpendicular to the direction of applied field. For the orientation dependence, see the SI.
