摘要：
The ligand ttd (ttd = 1, 4, 8, 9-Tetraaza-triphenylene-2, 3-dicarbonitrile) and a novel spin crossover complex [Fe (ttd)(2)(NCS)(2)] . H2O were synthesized, and characterized by elemental analysis, III, MS, and UV-vis spectroscopy. The temperature dependence of magnetic susceptibility shows that there are a little break between 150 similar to 190K and an unusual step transition with a 50K width between 190 similar to 240K. Compared with the other complexes with the resemble structure, it can be found that the influence of ligand is very notable.
