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.
