TZ;'%T: The primary purpose of the research was to confirm
the structural formulas attributed to these compounds on the
basis
of the method of preparat:'.on and of the chemical arid
spectrizi prop-
erties. The following compounds were subipcted tc X-ray
diffraction
analysis: diferrocenyl, b-is-I.-W-chloroferrcenyl),
bis-l-(Ilethyl-
ferrocenyl), bjs_l_(l'acc-:ylfcrrocenyl),
bis-l-(l'carbtnethoxyfcrro-
cenyl), and terferrocanyl (or:'1,11-diferroceiiylferrocene).
Their
.molecules ware found to bz centrally symmetrical, which bears
out
the coplanarity of the tWD cyclopentadiene rings. The tabulated
results. provide the follo~Ang data: 8tructural formula and
