Reversible single-crystal-to-single-crystal transition in Gd(iii) metal–organic frameworks induced by heat and solvents with a significant magnetocaloric effect

Triggered by heat and solvents, Gd( iii ) MOF undergo a SC–SC transition. JXUST-40a exhibits better stability and a larger magnetocaloric effect with −Δ S maxm = 26.65 J kg −1 k −1 under a 7 T applied field.
