Abstract

The cobalt complex [{K(18-crown-6)}₂(C₅H ₅)]- [Co(C₈H₁₂)₂](THF)₂ (3) has been synthesized and characterized by X-ray single-crystal structure determination. The crystal structure of Co(C₈H₁₂)(C ₈H₁₃) (2) has been reinvestigated and compared with the structure of 3. The 1, 5-cyclooctadiene (C₈H₁₂) and C ₈H₁₃ ligands are coordinated in an η⁴ and η³ fashion, respectively. The cyclopentadienyl anion in [{K(18-crown-6)}₂(C₅H₅)]⁺ in 3 is η⁵-coordinated to the two crown ether-encapsulated potassium cations.
