[N,N-Bis(2-pyridylmethyl)glycinato-⁴N,N',N'',O]dichloridoiron(III)-[N,N-bis(2-pyridylmethyl)glycine-⁴N,N',N'',O]dichloridozinc(II) (1/1)

Abstract: The title compound, [Fe(C₁₄H₁₄N₃O₂)Cl₂]·[ZnCl₂(C₁₄H₁₅N₃O₂)], is formulated as [Fe^III(bpg)Cl₂][Zn^IICl₂(bpgH)], where bpg is the tetradentate ligand N,N-bis(2-pyridylmethyl)glycine. The structure contains one crystallographically distinct complex with Fe^III and Zn^II 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-HO hydrogen bonds that include only one H atom per two complexes, consistent with the 1:1 disorder of Fe^III and Zn^II.
