X-ray crystal structure of [BPMEN(Cl)FeIIIOFeIII(Cl)BPMEN](ClO4)2 [BPMEN = N,N’-dimethyl-N,N’-bis(2-pyridylmethyl)ethane-1,2-diamine] and the assignment of its 1H NMR peaks in CD3CN

The complex [BPMEN(Cl)Fe^IIIOFe^III(Cl)BPMEN](ClO₄)₂ [BPMEN = N,N’-dimethyl-N,N’-bis(2-pyridylmethyl)ethane-1,2-diamine] was prepared and characterised by X-ray crystallography; the ¹H NMR peaks of this complex in CD₃CN were assigned based on the integration and proximity of particular protons to a paramagnetic centre.
