Russian Doll-like 3d-4f Cluster Wheels with Slow Relaxation of Magnetization.

ABSTRACT: The solvothermal reactions of LnCl₃·6H₂O and MCl₂·6H₂O (M = Co, Ni) with 2,2'-diphenol (H₂L¹) and 5,7-dichloro-8-hydroxyquinoline (HL²) gave three 3d-4f heterometallic wheel-like nano-clusters [Ln₇M₆(L¹)₆(L²)₆(µ₃-OH)₆(OCH₃)₆Cl(CH₃CN)₆]Cl₂·xH₂O (Ln = Dy, M = Co, x = 3 for 1; Ln = Dy, M = Ni, x = 0 for 2; Ln = Tb, M = Ni, x = 0 for 3) with similar cluster structure. The innermost Ln(III) ion is encapsulated in a planar Ln₆ ring which is further embedded in a chair-conformation M₆ ring, co
