摘要

We have attempted to characterize the magnetic and electrical properties of a new mixed-metal molecular material {NBu4[Ni(II)(0.5)Fe(II)(0.5)Fe(III)(ox)(3)]}(N) synthesized by the use of trioxalatoferrate as the building block. Mossbauer spectroscopy was utilized in order to understand local spin structures in this compound. The results indicate that the compound is a semiconducting ferrimagnet with T-N = 30 K and room temperature conductivity of 6 x 10(-15) Omega(-1) cm(-1) along with 1.8 eV activation energy under dark. The compound has no appreciable electrical response towards illumination.
