Hemi{tris(picolinic acid-κ2 N,O)iron(II)/tris(picolinato-κ2 N,O)iron(II)} hemi(tetrafluoroborate)

Abstract

The crystal structure of the title compound, [Fe(C6H4NO2)(C6H4.5NO2)(C6H5NO2)](BF4)0.5, is regarded as consisting of disordered mononuclear [FeII(C6H4.5NO2)3]0.5+ cations and tetrafluoroborate anions. The N,O-chelated Fe lies on a special position of site symmetry 3 and the acid H atom on a special position of site symmetry \overline{1}. The B atom is located on a special position of site symmetry \overline{3}. The disordered mononuclear units are linked through the acid H atom into a layer motif.
