Magnetic Spongelike Behavior of 3D Ferrimagnetic {[Mn-II(imH)](2)[Nb-IV(CN)(8)]}(n) with T-c=62 K
Fully reversible room temperature dehydration of 3D {Mn-2(II)(imH)(2)(H2O)(4)[Nb-IV(CN)(8)]center dot 4H(2)O}(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.
