Complex Compounds of Iron(II) with 2,2'-Bipyridylamine and Boron Cluster Anions [BnHn]2– (n = 10, 12)

The complexation of iron(II) with 2,2'-bipyridylamine (BPA) in the presence of boron cluster anions [B n H n ] 2– ( n = 10, 12) in aqueous solutions is studied. Mixed-ligand complexes [Fe(BPA) 2 -(H 2 O) 2 ][B n H n ] ( n = 10 ( I ), n = 12 ( II )) with boron cluster anions in the outer sphere are synthesized. The reagent ratio does not affect the compositions and structures of the synthesized compounds. Compounds I and II are identified by elemental analysis and IR spectroscopy. The structure of the [Fe(BPA) 2 -(H 2 O) 2 ][B 10 H 10 ] ∙ 3H 2 O complex ( I ∙ 3H 2 O) is determined by X-ray diffraction analysis (СIF file CCDC no. 1962445).
