Abstract

A chiral cluster CpS14Fe4S6 (CpS1 = η5-C5H4(SiMe3)) was found to be fluxional due to the skeletal inversion. The line shape analysis for variable temperature 1H NMR spectra (400 MHz, toluene-d8) yielded activation parameters: ΔH ‡ = 63.7 ± 16.0 kJ mol-1 and ΔS ‡ = -20.8 ± 16.0 J mol-1 K-1. A plausible mechanism for the dynamic behavior is proposed.
