The lithi ation of ferrocenylphosphane Fc-PH 2 (Fc = C5 H4 FeC5H 5) has been reinvestiga ted and both Fc- PHLi and Fc-PLi 2 have been identi ﬁ ed by N MR-spectroscopy. The lithia ted phosph anide s have be en conver ted to the corresponding mono and bis(silylated) spec ies the latter of which gave synth etic access to an oligomer in wh ich three ferrocene units are symme trically connec ted by phosph aalke ne unit s. The charge distri bution within this oli gomer and its isomer s has been ana lyzed using DFT calculat ions which indicates that the iron atom of the central metal locene unit is slightly more positive than the terminal ones. The se ﬁ nding s are sup ported exp eriment ally by Mößbauer spectroscopy and cyclic voltammetry.
