Fully reversible room temperature dehydration of 3D {Mn^II₂(imH)₂(H₂O)₄[Nb^IV(CN)₈]·4H₂O}_n (1; imH = imidazole) of T_c = 25 K results in the formation of 3D ferrimagnet {[Mn^II(imH)]₂[Nb^IV(CN)₈]}_n (2), with T_c = 62 K, the highest ever known for octacyanometalate-based compounds. The dramatic magnetostructural modifications in 2 provide the first example of magnetic spongelike behavior in an octacyanometallate-based assembly.
