Title: Hydrogen-bonded 2D network structure and abrupt spin transition with thermal hysteresis of iron(III) complexes [FeIII(Him)2(3-MeOsalen)]·H2O·EtOH·X (Him=imidazole, 3-MeOsalen=N,N′-bis(3-methoxysalicylidene)ethylenediaminato, and X=PF6, AsF6, SbF6)
Abstract: Spin crossover (SCO) iron(III) complexes exhibiting thermal hysteresis, [FeIII(Him)2(3-MeOsalen)]·H2O·EtOH·X (Him = imidazole, 3-MeOsalen = N,N′-bis(3-methoxysalicylidene)ethylenediaminato, and X = PF6, AsF6, SbF6), were synthesized in ethanol. The FeIII ion has an octahedral coordination geometry with N2O2 donor atoms of the planar tetradentate ligand (3-MeOsalen) and two nitrogen atoms of two imidazoles at the axial positions. Through H2O and EtOH the complex-cations are assembled into a hydrogen-bonded 2D network structure and the anion X is accommodated in the void of the 2D network. The temperature dependences of the magnetic susceptibilities revealed an abrupt and two-step spin transition with thermal hysteresis for the PF6 and AsF6 salts.
