| Abstract: | Electrical and magnetic properties of {Ru(bpy)3]Fe(dca)3]2}n (bpy=2,2′-bipyridine, dca=dicyanamide) have been studied. The compound is a non-extrinsic type of semiconductor and paramagnetic in nature. Mössbauer spectroscopy has established the presence of high spin Fe(II) as one major species in this compound, and no high spin-low spin transition of Fe(II) was detected down to 80 K under dark. The photo-response of electrical conductivity with time shows interesting behavior with repeated exposure. |
