H/D isotope effect and magnetic properties of cyanide-bridged Nd(III)-Fe(III) complex

Abstract

We have prepared four H/D isotope forms of Nd(DMF)4(H2O)3Fe(CN)6·H2O (DMF = N,N-dimethylformamide) by using D2O or DMF-d1. Temperature dependence of magnetization exhibits H/D isotope effects resulting from intermolecular hydrogen bonds. Temperature dependence of Fe 2p3/2 and 2p1/2 XAS and 57Fe Mössbauer spectra suggested that the influence of coordination environment could be distiguished from the influence of crystal lattice based on preliminary crystallographic results.
