Synthesis and characterization of Fe(III)(3-CH3O-qsal)2PF6 · nH2O (n = 0, 2)

Compounds FeIII(3-CH3O-qsal)2PF6 · nH2O (n = 0, 2) (1, 1 · 2H2O) were synthesized and characterized: the structure of 1 and the magnetic properties of both compounds were determined. Compound 1 · 2H2O presents properties characteristic of high-spin Fe(III), while 1 presents properties of low-spin Fe(III) with an onset of a gradual spin crossover at ca. 300 K.

Graphical abstractCompounds FeIII(3-CH3O-qsal)2PF6 · nH2O (n = 0, 2) were synthesized and characterized. The hydrated one present properties characteristic of high-spin Fe(III), while the dry one of low-spin Fe(III). The dry compound has a beginning of spin crossover at high temperatures.Figure optionsDownload full-size imageDownload as PowerPoint slide
