Molecular-based magnet with two magnetic transition temperature: A Prussian-blue analogue Mn3[Cr(CN)6]2·12H2O

A Prussian-blue analogue Mn3[Cr(CN)6]2·12H2O has been prepared and characterized by single crystal X-ray analysis and magnetic measurements. The complex has a disordered face-centered cubic lattice and shows two magnetic transition temperatures of 74 and 61 K.
