   The reduction potentials (reported vs. Fc + /Fc) for a series of Cp′ 3 Ln complexes (Cp′ = C 5 H 4 SiMe 3 , Ln = lanthanide) were determined via electrochemistry in THF with [ n Bu 4 N][BPh 4 ] as the supporting electrolyte. The Ln( iii )/Ln( ii ) reduction potentials for Ln = Eu, Yb, Sm, and Tm (−1.07 to −2.83 V) follow the expected trend for stability of 4f 7 , 4f 14 , 4f 6 , and 4f 13 Ln( ii ) ions, respectively. The reduction potentials for Ln = Pr, Nd, Gd, Tb, Dy, Ho, Er, and Lu, that form 4f n 5d 1 Ln( ii ) ions ( n = 2–14), fall in a narrow range of −2.95 V to −3.14 V. Only cathodic events were observed for La and Ce at −3.36 V and −3.43 V, respectively. The reduction potentials of the Ln( ii ) compounds [K(2.2.2-cryptand)][Cp′ 3 Ln] (Ln = Pr, Sm, Eu) match those of the Cp′ 3 Ln complexes. The reduction potentials of nine (C 5 Me 4 H) 3 Ln complexes were also studied and found to be 0.05–0.24 V more negative than those of the Cp′ 3 Ln compounds.

   Three new polynuclear clusters with the formulae [Mn₁₀O₄(OH)(OMe){(py)₂C(O)₂}₂{(py)₂C(OMe)(O)}₄(MeCO₂)₆](ClO₄)₂(1), Na[Mn₁₂O₂(OH)₃(OMe){(py)₂C(O)₂}₆{(py)₂C(OH)(O)}₂(MeCO₂)₂(H₂O)₁₀](ClO₄)₈(2) and [Mn₁₂O₄(OH)₂{(py)₂C(O)₂}₆{(py)₂C(OMe)(O)}(MeCO₂)₃(NO₃)₃(H₂O)(DMF)₂](NO₃)₂(3) were prepared from the combination of di‐2‐pyridyl ketone, (py)₂CO, with the aliphatic diols (1,3‐propanediol (pdH₂) or 1,4‐butanediol (1,4‐bdH₂)) in Mn carboxylate chemistry. The reported compounds do not include the aliphatic diols employed in this reaction scheme; however, their use is essential for the formation of1–3. The crystal structures of1–3are based on multilayer cores which, to our knowledge, are reported for the first time in Mn cluster chemistry. Direct current (dc) magnetic susceptibility studies showed the presence of dominant antiferromagnetic exchange interactions within1–3. Alternating current (ac) magnetic susceptibility studies revealed the presence of out‐of‐phase signals below 3.0 K for2and3indicating the slow relaxation of the magnetization vector, characteristic of single‐molecule magnets; theU_effvalue of2was found to be 23 K and the preexponential factorτ₀~7.6×10⁻⁹ s.
