Notes:
Detailed 57Fe Mossbauer experiments over the range 85〈T〈210 K have been carried out on the tetra-carbonyl iron derivative of C60(I) as well as on several related organometallic solids. The observed isomer shift and quadrupole splitting parameters are consistent with a bonding interaction between the metal center and the ligand which involves a single carbon–carbon double bond of the buckminsterfullerene. The temperature dependence of the recoil-free fraction, compared to analogous data for maleic anhydride Fe(CO)4(II), suggests that the two previously observed low frequency lattice modes in C60 persist in I. Contrary to expectations, there is no significant temperature-dependent vibrational anisotropy (Gol'danskii–Karyagin effect) evident in the above temperature range. © 1996 American Institute of Physics.
