An object of the present invention is to enable the synthesis of various fluorine-containing compounds having an organic group at both terminals of their tetrafluoroethylene structure (—CF.sub.2—CF.sub.2—). The present invention provides a fluorine-containing complex compound including a fluorine-containing organic metal compound represented by formula (1a):
R.sup.1—CF.sub.2—CF.sub.2-M.sup.1  (1a)
wherein M.sup.1 is a metal selected from the group consisting of copper, zinc, nickel, iron, cobalt, and tin; and R.sup.1 represents an organic group, and at least one ligand selected from the group consisting of pyridine ring-containing compounds and phosphines.
