Crystal structure and spin state of Fe0.5Co0.5(NCS)2(bpa)2

摘要

Fe(NCS)2(bpa)2, Co(NCS)2(bpa)2, and Fe0.5Co0.5(NCS)2(bpa)2 were synthesized. X-ray structural analysis revealed that the structure was the same among the three complexes. Although the metal-ligand distance in the mixed crystals was shorter than the distance in Fe(NCS)2(bpa)2 and was similar to that in Co(NCS)2(bpa)2, the spin state remained temperature-independent FeII high-spin state in 57Fe Mössbauer spectra.
