Abstract
The extremely air-sensitive 19-electron [Fe(I)Cp hexaalkylbenzene)] co mplexes (alkyl = n-propyl, n-butyl, n-pentyl) have been synthesized; v ariable-temperature Mossbauer data indicate a drastic decrease of the quadrupole splitting upon increasing temperature which does not corres pond to a Boltzmann population of the upper Kramer's doubler due to th e 'chain effect'. It is proposed that an increasing proportion of the 17-electron Fe(I) state is involved as the chain length increases.
