Synthesis of Iron and Cobalt Complexes of a Ferrocene-Linked Diphosphinoamide Ligand and Characterization of a Weak Iron–Cobalt Interaction
Abstract
A ferrocene-based bis(phosphinoamine) fc(NHP<sup><i>i</i></sup>Pr<sub>2</sub>)<sub>2</sub> has been deprotonated and used in salt metathesis reactions to form dimeric complexes ([fc(NP<sup><i>i</i></sup>Pr<sub>2</sub>)<sub>2</sub>]M)<sub>2</sub> (M = Fe, Co). A novel coordination environment for Co(II) is observed including a weak but significant Fe–Co interaction, which was characterized using X-ray crystallography, Mössbauer spectroscopy, and VT-magnetometry. Density functional theory (DFT) calculations including natural bond order analysis provides further support for the interaction and suggests a combination of Fe → Co and Co → Fe interactions- Dataset
