Abstract

To expand the range of donor atoms known to stabilize 4fⁿ5d¹ Ln(II) rare-earth metal (Ln) ions beyond the C, N, and O first row main group donor atoms, the Ln(III) sulfur donor terphenylthiolate iodide complexes, Ln^III(SAr^iPr6)₂I (Ar^iPr6 = C₆H₃-2,6-(C₆H₂-2,4,6-ⁱPr₃)₂, Ln = La, Nd) were reduced to form Ln^II(SAr^iPr6)₂ complexes. These Ln(II) species were structurally characterized, analyzed by density functional theory (DFT) calculations, and compared to Tm(SAr^iPr6)₂, which was synthesized from TmI₂(DME)₃.
