Abstract
A SCO iron(III) complex [FeIII(Him)2(4MeOhapen)]CF3SO3 was synthesized, where Him = imidazole and 4-MeOhapen = N,N′-bis(2-oxy-4-methoxyacetophenylidene)ethylenediamine. FeIII ion has an octahedral coordination geometry with N2O2 donor atoms of the equatorial tetradentate ligand (4-MeOhapen) and two nitrogen atoms of two imidazoles (Him) at the axial positions. The adjacent cations are bridged by CF3SO3 - ion through NH⋯O hydrogen bonds between Him and CF3SO3 - to give a one-dimensional chain structure {[FeIII(Him)2(4MeO-hapen)]CF3SO3}1. The magnetic susceptibility measurements showed that complex exhibits an abrupt spin transition between a single HS phase and a symmetry-breaking [HS-HS-HS-LS] phase and another transition around 80 K. The single-crystal X-ray analyses at 296 and 150 K revealed the structures at a single HS and [HS-HS-HS-LS] states.
