Abstract
We have investigated the spin-crossover behavior of the triazole-bridged on e-dimensional Fe(II) complexes, [Fe(4-NH(2)trz)(3)](o-, m-, p-NH2C6H4SO3)(2 ) . 2H(2)O by means of Fe K-edge EXAFS and magnetic susceptibility measurem ents. In this system, the transition temperature and the hysteresis width a re drastically varied by the isomerism of counter anion o-, m-, p-NH2C6H4SO 3-. Moreover, we have synthesized [Fe(4-NH(2)trz)(3)](SP150)(2) in which SP 150 is known for photo-isomerization, and have investigated its spin-crosso ver behavior.
