A Neutral Dy(II) Bis(amide): Synthesis, Magnetism, and a P₄^2- Complex.

ABSTRACT: Reaction of DyCl₃ with KNHAr*, where Ar* = 2,6-Ar₂C₆H₃ and Ar = 2,4,6-ⁱPr₃C₆H₂, results in the formation of ClDy(NHAr*)₂, which can be reduced with KC₈ in THF to room temperature stable dysprosium(II) Dy(NHAr*)₂, where Ar rings of the NHAr* ligand chelate and bind to the metal center to give a black sandwich complex. The redox potential for the reversible Dy^2+/3+-couple was found to be -1.094 ± 0.001 V with respect to FeCp₂^+/0 as 0.000 V. The complex was examined by CASSCF calculations, which suggest the non-Kramer's ion has an 4f⁹5d¹-configuration with little to no s-orbital participation. The reaction of Dy(
