D. Braga et al., ON THE MOLECULAR-STRUCTURE OF [FE-3(CO)(12)] IN THE SOLID-STATE, Journal of organometallic chemistry, 464(2), 1994, pp. 30000039-30000041
The determination of precise, low-temperature crystal structures of [F
e-3(CO)(12)] has shown that, on decreasing the temperature, the bridgi
ng ligands become progressively more symmetric, the bridged Fe-Fe bond
shortens and the atomic displacement parameters show a congruent beha
viour with temperature.
