摘要
Spin transition complexes are of great interest because of their potential application in molecular based electronic devices such as optical memory and switches. A novel linear polynuclear spin transition complex [Fe (PhCH = Ntrz)(3)] (BF4)(2). 3H(2)O (where PhCH=Ntrz stood for the Schiff base condensed by 4-NH2-1, 2, 4-triazole and benzaldehyde) was synthesized and characterized by elemental analysis, molar conductance, IR and UV-Vis spectra, magnetic measurements and temperature-dependence optical detection. The spin transition occurred at 105 similar to 235 K with hysteresis and pronounced thermochromism, T-c up arrow =180 K, T-c down arrow =169 K, hysteresis width 11 K.
