A thermoresponsive Fe-Co based discrete Prussian Blue Analogue (PBA) with general formula [Fe(Tp)(CN)3]2[Co{en(Bn)py}]2(ClO4)2 •4MeOH•4H2O i.e. [1•4MeOH•4H2O] is reported, which discloses a sharp and high temperature ETCST along with the wide...

The new 3D Hofmann-type coordination polymer [Fe(dpyu){Pt(CN) 4 }]•9H 2 O [dpyu = 1,3-di(pyridin-4-yl)urea] exhibits reversible interchange between two-and one-step spin-crossover behavior, associated with desorption/resorption of lattice water molecules. Solvent water removal also induces an increase of the spin-transition temperature, indicating strong lattice cooperativity, observed for the first time in a 3D Hofmann-type coordination polymer.
