Redox and guest tunable spin-crossover properties in a polymeric polyoxometalate.

ABSTRACT: A bifunctionalized polyoxometalate (POM), [V₆O₁₉(C₁₆H₁₅N₆O)₂]^2-, which contains a redox active hexavanadate moiety covalently linked to two tridentate 2,6-bis(pyrazol-1-yl)pyridine (1-bpp) ligands, has been prepared and characterized. Reaction of this hybrid molecule with Fe(ii) or Zn(ii) ions produces crystalline neutral 1D networks of formula Fe[V₆O₁₉(C₁₆H₁₅N₆O)₂]·solv (2) and Zn[V₆O₁₉(C₁₆H₁₅N₆O)₂]·solv (3) (solv = solvent molecules). Magnetic properties of 2 show an abrupt spin-crossover (SCO) with the temperature, which can be induced by light irradiation at 10 K (Light-Induced Ex
