complexes [(η5-Cp)(dppe)Fe}2μ2-(NC-X-CN)}]n+ (n = 0, 2) in which X = [−B10H8−]2–, −C6H4–, −C8H12–, and −C2B10H10– was investigated by spectroscopic (UV–vis and IR), electrochemical (CV and DPV), and single-crystal XRD methods. All experimental results were supported by a DFT computational analysis (B3LYP/Def2SVP) of model complexes that included two other closo-boranes: X = −C2B8H8– and [−B12H10−]2–
