摘要

Two iron(II) compounds with the general formula of [Fe(phen-TPE)₂(NCX)₂] ⋅ Y (phen-TPE=3-(tetraphenylethylene)-1,10-phenanthroline; X=S and Y=2DMF for 1 ⋅ 2DMF; X=Se and Y=DMF for 2 ⋅ DMF) were synthesized and characterized by single-crystal X-ray crystallography and magnetic measurements. Both compounds exhibited thermal-induced complete one-step spin-crossover (SCO) behavior with the critical transition temperatures of 210 K and 260 K for 1 ⋅ 2DMF and 2 ⋅ DMF, respectively. The SCO behavior of these two isomorphic compounds depended significantly on robust intermolecular π⋅⋅⋅π interactions, NCX⁻ groups and solvent molecules.
