A novel tetraoxolene-bridged Fe two-dimensional honeycomb layered compound, (NPr4)(2)[Fe-2(Cl(2)An)(3)]center dot 2(acetone)center dot H2O (1), where Cl(2)An(n-) = 2,5-dichloro-3,6-dihydroxy-1,4-benzoquinonate and NPr4+ = tetrapropylammonium cation, has been synthesized. 1 revealed a thermally induced valence tautomeric transition at T-1/2 = 236K (cooling)/237K (heating) between Fem+ (m = 2 or 3) and Cl(2)An(n-) (n = 2 or 3) that induced valence modulations between [(FeHSFeHSIII)-Fe-II(Cl(2)An(2-))(2)(Cl(2)An(.3-))](2-) at T>T-1/2 and [(FeHSFeHSIII)-Fe-III(Cl(2)An(2-))(Cl(2)An(.3-))(2)](2-) at T
