文摘

The interaction of ferrocene with tin(IV) o-benzosemiquinonato complexes in acetonitrile results in a reversible electron transfer (ET) from ferrocene to the redox-active ligand with the formation of electron-transfer complexes [(3,6-Cat)SnBr₃]^{鈭?/sup>[Cp₂Fe]+ (1) and [(3,6-Cat)(3,6-SQ)SnCl₂]鈭?/sup>[Cp₂Fe]+ (2), where 3,6-Cat is the 3,6-di-tert-butyl-catecholate dianion and 3,6-SQ is the 3,6-di-tert-butyl-o-benzosemiquinonato radical anion. The ET process and the solvent effect in the system ferrocene鈥?i>o-benzosemiquinonato tin(IV) complexes were investigated on the basis of a combination of spectroscopic and X-ray diffraction methods. The molecular structures of 1 and 2 were confirmed by X-ray analysis. Complex 2 demonstrates the ferromagnetic coupling in the linear chain alternating 路路路D+鈥?/sup>A鈥撯€?/sup>D+鈥?/sup>A鈥撯€?/sup>路路路 motif.}
