The magnetic properties of 1 reveal very weak antiferromagnetic interactions between the Gd III ions, which give rise to a record magnetocaloric effect at low applied magnetic fields and low temperatures. The magnetic entropy change reaches −Δ S m = 29.3 J kg –1 K –1 for full demagnetization from B = 1 T at T = 0.5 K.
