Abstract

Facial-and meridional-isomers of tris[benzyl(2-methylimidazol-4- ylmethylidene)amine]iron(II) chloride hexafluorophosphate with the formulas of fac-[Fe(HL^Me-Benz)₃]Cl·PF ₆·EtOH· H₂O (1) and mer-[Fe(HL ^Me-Benz)₃]Cl·PF₆·1.5H ₂O (2) were selectively crystallized in ethanol and methanol, respectively. All three imidazole groups in both the fac-and mer-[Fe(HL ^Me-Benz)₃]²⁺ cations are hydrogen-bonded to neighboring Cl^- ions and give the assembly structures. The compounds differ, however, in that 1 has a discrete cubane-like tetranuclear cluster, while 2 forms a two-dimensional (2D) network structure. The magnetic susceptibilities data revealed that 1 and 2 are spin crossover complexes.
