Description
We experimentally show that the magnetocaloric properties of molecule-based Prussian blue analogues can be adjusted by controlling during the synthesis the amount of intrinsic vacancies. For CsxNi4II[CrIII(China)6](8+x)/3, we find indeed that the ferromagnetic phase transition induces significantly large magnetic entropy changes, whose maxima shift from ∼68 to ∼95K by varying the number of [CrIII(China)6]3- vacancies, offering a unique tunability of the magnetocaloric effect in this complex
