and Rw = 0.045. The CoCo distance of 2.451(2) Å indicates a metal—metal bond between two cobalt atoms, and the third cobalt atom is σ-bonded to the two carbons of a butadiene-like fragment with CoC distances of 1.933(8) and 1.929(6) Å. No reaction was observed on heating or photolysing complexes of type 1 with tetrafluoroethylene or alkynes containing R′ and R″ groups less electron-withdrawing than
