[N,N-Bis(2-pyridylmethyl)glycinato-κ4N,N′,N′′,O]dichloridoiron(III)–[N,N-bis(2-pyridylmethyl)glycine-κ4N,N′,N′′,O]dichloridozinc(II) (1/1)

Abstract

The title compound, [Fe(C14H14N3O2)Cl2]·[ZnCl2(C14H15N3O2)], is formulated as [FeIII(bpg)Cl2][ZnIICl2(bpgH)], where bpg is the tetradentate ligand N,N-bis(2-pyridylmethyl)glycine. The structure contains one crystallographically distinct complex with FeIII and ZnII atoms present in a 50:50 ratio in a single-atom site. The non-coordinated O atoms of the carboxyl groups of bpg meet across crystallographic inversion centres, forming O—H...O hydrogen bonds that include only one H atom per two complexes, consistent with the 1:1 disorder of FeIII and ZnII.
