New iron(II) complexes with 2,6-bis(benzimidazol-2-yl)pyridine (L) and closo-borate(2–) anions—[FeL2 ][B10H 10] ⋅ 2H 2 O and [FeL2 ][B12 H12 ] ⋅ H 2O—have been synthesized. The complexes have been characterized by static magnetic susceptibility measurements, electronic (diffuse reflectance spectra), IR, and EXAFS spectroscopy, and X-ray diffraction analysis. A study of the μeff(T) dependence in the temperature range 80–500 K has shown that the complexes exhibit a high-temperature spin crossover 1 А1 ⇔ 5 Т 2.
