New mixed crystals, Fe(NCS) x (NCBH3)(2−x)(bpp)2, (bpp = 1,3–bis(4–pyridyl)propane) were synthesized. The formation of mixed crystals was confirmed by powder X-ray diffraction patterns and single crystal X-ray structural analysis. Elemental analyses showed that all Fe(NCS) x (NCBH3)(2−x)(bpp)2 samples had more Fe(NCS)2 unit than the preparation fraction. 57Fe Mössbauer spectroscopy revealed that all the spectra consist of only Fe(NCS)2 unit and Fe(NCBH3)2 unit. And the fraction of low-spin state in the Fe(NCBH3)2 unit changed with the change of x. The results suggested that the high spin site of Fe(NCS)2 unit affects the spin state of Fe(NCBH3)2 unit.
