Slow magnetic relaxation in a high-spin pentacoordinate Fe(iii) complex†
Abstract
A mononuclear pentacoordinate iron(III) complex shows slow magnetic relaxation with three relaxation channels. The high-frequency relaxation time of the order of microseconds is prolonged on cooling in accordance with the direct and Raman processes. The low frequency relaxation time is little dependent on temperature and varies in the range τ(LF) = 0.52–0.79 s.
