Temperature Dependence of 57Fe-Mössbauer Spectra for a Trinuclear System

Abstract

Abstract.57 Fe Mӧssbauer spectra were recorded for 1'-terpyridine ferrocenecarboxylic acid and [bis(1'-terpyridine ferrocenecarboxylic acid) Fe(II)] 2+ in the temperature range 7 -293 K. The temperature dependence of the Quadrupole Splitting, Isomer Shift and Debye-Waller factor are discussed. The Debye temperature for the iron nuclei in the investigated compounds was determined.
