The magnetocaloric effect (MCE) in a novel Mn2-[Nb(CN)8] molecular magnet with a two-step magnetic sponge behavior and large shifts in the ferrimagnetic ordering temperature (Tc) as a result of dehydration is reported. The field dependence of MCE at Tc for the “as synthesized”, partially and fully dehydrated phases is consistent with the values of the critical exponents derived from the magnetization data.
