Abstract

The study of the spin-crossover phenomenon is an important field of magnetochemistry, which has attracted much attention. A new ligand, 2-methyl-1,4,8,9-tetraaza-triphenylene (mtt) and its complex, [Fe(mtt)₂(NCS)₂]·2.5H₂O, exhibiting high temperature spin crossover were prepared. Elemental analysis, ¹H NMR, infrared spectrum, electrospray ionization mass spectrum and ultraviolet spectrum were used to study the structure of the ligand and the complex. The variable-temperature magnetic susceptibility study shows that the temperatures of spin transition are T_c↑=347 K and T_c↓=343 K, respectively, and the hysteresis loop is 4 K, which is the highest spin crossover temperature in the kind of [Fe(L)₂(NCS)₂] system. By comparing the complex with other similar structural complexes, it is revealed that the modification of ligand will influence greatly the critical temperature and hysteresis loop of spin crossover.

Key words: ligand, magnetic susceptibility, spin crossover, spin transition, molecular material
