Magnetic properties of monomeric and polymeric stannolediide yttrium and erbium complexes.

ABSTRACT: Lanthanide sandwich complexes are promising candidates for single-molecule magnets, owing to their magnetic anisotropy and slow relaxation of magnetization. Here we show the synthesis and characterization of the polymeric yttrium and erbium complexes ligated by cyclooctatetraendiide and stannolediide ligands. The molecular structures showed the formation of one-dimensional-coordination polymers with the molecular formula of C₄₀H₅₆KOSi₂SnLn (Ln = Y, Er), which resemble a trapezoidal wave. Upon encapsulation of the K cations with 2.2.2-cryptand, the respective monomeric sandwich complexes having the molecular formula of C₅₇H₈₇KN₂O₆Si₂SnLn (Ln = Y, Er) were obtained. The diamagnetic yttrium complexes were
