We report on the magnetocaloric properties of two molecule-based hexacyanochromate Prussian blue analogs, nominally CsNiII [CrIII (CN) 6] (H2 O) and Cr3 II [CrIII (CN) 6] 2 12 (H2 O). The former orders ferromagnetically below TC 90 K, whereas the latter is a ferrimagnet below TC 230 K. For both, we find significantly large magnetic entropy changes Δ Sm associated with the magnetic phase transitions. Notably, our studies represent an attempt to look at molecule-based materials in terms of the magnetocaloric effect for temperatures well above the liquid helium range.
