The title compound, cyclooctadienyl potassium tetrahydrofuranate was prepared by the reaction of cycloocta-1,5-diene with metallic potassium in tetrahydrof u-ran(THF) in the presence of triethylamine. Its crystal structure was determined by a low temperature X-ray diffraction analysis method. The crystal is monoclinic with space group Pc,a=6. 192(3),b=9. 444(8),c=14. 543(1) A ,β=94. 92(5)°,V = 847. 24 A3,Z = 2,DC= 1. 14 g/cm3 and μ(MoKa) = 5. 58cm-1. The structure was solved by heavy-atom methods and refined by least-squares to a final R value of 0. 049. The potassium cations, each with two complex THF molecules attached,are linked by bridging cyclooctadienyl an-ions,while the anions are connected to the bridging cations to form a puckered chain.
