    Abstract

    The first example of a ferrocene-chelating heteroscorpionate, [Li­(THF)<sub>2</sub>]­[fc­(PPh<sub>2</sub>)­(BH­[(3,5-Me)<sub>2</sub>pz]<sub>2</sub>)] ((fc<sup>P,B</sup>)­Li­(THF)<sub>2</sub>, fc = 1,1′-ferrocenediyl) is described. Starting from a previously reported compound, fcBr­(PPh<sub>2</sub>), a series of ferrocene derivatives, fc­(PPh<sub>2</sub>)­(B­[OMe]<sub>2</sub>), [Li­(OEt<sub>2</sub>)]­[fc­(PPh<sub>2</sub>)­(BH<sub>3</sub>)], [Li­(THF)<sub>2</sub>]­[fc­(PPh<sub>2</sub>)­(BH­[(3,5-Me)<sub>2</sub>pz]<sub>2</sub>)] (pz = pyrazole), was isolated and characterized. Compound (fc<sup>P,B</sup>)­Li­(THF)<sub>2</sub> allowed the synthesis of the corresponding nickel and zinc complexes, (fc<sup>P,B</sup>)­NiCl, (fc<sup>P,B</sup>)­NiMe, (fc<sup>P,B</sup>)­ZnCl, and (fc<sup>P,B</sup>)­ZnMe. All compounds were characterized by NMR spectroscopy, while the zinc and nickel complexes were also characterized by X-ray crystallography. The redox behavior of (fc<sup>P,B</sup>)­NiCl, (fc<sup>P,B</sup>)­NiMe, (fc<sup>P,B</sup>)­ZnCl, and (fc<sup>P,B</sup>)­ZnMe was studied by cyclic voltammetry and supported by density functional theory calculations
