Sb. Zhang et al., SYNTHESIS AND CRYSTAL-STRUCTURE OF TETRAHYDROFURFURYLCYCLOPENTADIENYLSODIUM TETRAHYDROFURANATE COMPLEX, Polyhedron, 12(23), 1993, pp. 2771-2774
A tetrahydrofurfurylcyclopentadienyl sodium tetrahydrofuranate complex
was prepared by the reaction of tetrahydrofurfurylcyclopentadiene wit
h metallic sodium in THF. Its crystal structure was determined by X-ra
y analysis. In the crystal. the tetrahydrofuranate complex C4H7OCH2C5H
4Na . THF adopts a puckered chain structure with an eta5-(C4H7OCH2)C5H
4 ring connected by a bridging Na(THF) unit. The oxygen in the eta5-(C
4H7OCH2)C5H4 ring is coordinated to the sodium atom.
