Single-molecule Magnet Properties of Silole- and Stannole-ligated Erbium Cyclo-octatetraenyl Sandwich Complexes.

ABSTRACT: The synthesis, structures and magnetic properties of an η⁵-silole complex and an η⁵-stannole complex of erbium are reported. The sandwich complex anions [(η⁵-Cp^Si)Er(η⁸-COT)]^- and [(η⁵-Cp^Sn)Er(η⁸-COT)]^-, where Cp^Si is [SiC₄-2,5-(SiMe₃)₂-3,4-Ph₂]^2- (1_Si), Cp^Sn is [SnC₄-2,5-(SiMe₃)₂-3,4-Me₂]^2- (1_Sn) and COT=cyclo-octatetraenyl, were obtained as their [K(2.2.2-cryptand)]⁺ salts and found to be isostructural, with remarkably similar bond lengths and angles, differing only in the lengths of the Er-E interactions (E=Si, Sn).
