Alkali Metal Based Triimidosulfite Cages as Versatile Precursors for Single‐Molecule Magnets

Abstract: Based on the potassium [{S(tBuN)2(tBuNH)}2K3(tmeda)‐K3{(HNtBu)(NtBu)2S}2] (1) and sodium precursors [S(tBuN)3(thf)3‐Na3SNa3(thf)3(NtBu)3S] (2), [S(tBuN)3(thf)3Na3{(HNtBu)(NtBu)2S}] (3) and [(tmeda)3S‐{Na3(NtBu)3S}2] (4) the syntheses and magnetic properties of three mixed metal triimidosulfite based alkali‐lanthanide‐metal‐cages [(tBuNH)Dy{K(0.5tmeda)}2{(NtBu)3S}2]n (5) and [ClLn{Na(thf)}2{(NtBu)3S}2] with Ln=Dy (6), Er (7) are reported. The corresponding potassium (1) and sodium (2–4) based cages are characte… Show more

“…[18] A true first-order SOC is observed for a Co II ion in a weak octahedral ligand field with a 4 F free ion ground state term, which splits into a 4 T1g ground state term (Figure 1.2.a). Applying a tetragonal distortion (D4h) results in two states, labeled as 4 A2g and…”

“…𝜏 −1 = 𝐴𝐻 𝑛 1 𝑇 + 𝐶𝑇 𝑛 2 + 𝜏 0 −1 exp (− 𝑈 eff 𝑘 B 𝑇 ) + 𝑄 (1)(2)(3)(4) where T devotes to the specific temperature dependency and 𝐴, 𝐶, 𝜏 0 −1 , and 𝑄 are treated as freeto-fit parameters since their determination is highly challenging. The four contributing terms of the relaxation processes are outlined below in detail.…”
