文摘
A ferrocene-based bis(phosphinoamine) fc(NHPiPr2)2 has been deprotonated and used in salt metathesis reactions to form dimeric complexes ([fc(NPiPr2)2]M)2 (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.
