The reaction of t-BuLi with a fluoroalkynyl-germane produces the title
compound, 1. Single-crystal X-ray analysis shows the Ge=C bond length
to be 1.783(2) Angstrom. The Ge atom is somewhat pyramidalized, and t
he Ge=C=C bond angle (159.2 degrees) reveals a bent structure at the c
entral carbon atom.
