Magnetic susceptibility and magnetisation data were collected on powdered microcrystalline samples of 1-2 using a Quantum Design PPMS Dynacool. Susceptibility data were collected in the T = 2-300 K range under an applied magnetic field, B = 0.1 T. Magnetisation data were collected in the T = 3-10 K and B = 0.5-9.0 T ranges. A unit cell check was performed prior to measurement. Powdered samples were restrained in eicosane.
