Steady Iron_sulfur nanoclusters were synthesized in the mixed solvent of water and ethanol with surface modification method. The structure and properties of nanoclusters were investigated by Uv_vis ,FT_IR,TG,DTA, TEM ,SAED and DFM. The results indicated that PyDDP had a strong modificatory property on iron_sulfur Clusters. Average granularity with about 7?nm or so, Uv_vis and DFM tended to congregate in chloroform solvent.
