Abstract

THF-solvated KC₅Me₅ and KC₅Me₄SiMe₂CH₂CH=CH₂ complexes crystallize with extended structures that provide information on bent metallocenes containing potassium, [(μ-C₅R₅)K(μ-C₅R₅)]⁻. The substructures of [(THF)K(μ-C₅Me₅)]_n, [(THF)₂K(μ-C₅Me₅)]_n, and [(THF)K(μ-C₅Me₄SiMe₂CH₂CH=CH₂)]_n display (μ-C₅R₅)K(μ-C₅R₅) angles of 137.9–143.7°. The olefin substituent in [(THF)K(μ-C₅Me₄SiMe₂CH₂CHCH₂)]_n approaches potassium with K⋯C distances of 3.58 and 4.20 Å.
