Titanocene, zirconocene, and hafnocene dichlorides were reduced in the presence of terminally disubstituted 1,6-heptadiyne or 1,7-octadiyne to produce dicyclopentadienylmetallabicyclooctadienes and -nonadienes. The compounds were characterized by elemental analysis and 1H and 13C NMR spectrometry, and (C5H5)2HfC7H6[Si(CH3)3]2 was characterized by X-ray diffraction techniques. The compounds crystallized
