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 charac terized by elemental analysis, IR, MS, and UV-vis spectroscopy. The temperature dependence of magnetic susceptibility shows that there are a little break betwe en 150～190K and an unusual step transition with a 50K width between 190～240K. Compared with the other complexes with the resemble structure, it can be found t hat the influence of ligand is very notable.
