Trans Structure

57Fe Mössbauer spectra are reported for neutral FeX2(diars)2 (X = Cl, Br, I, NCS) complexes and newly prepared cationic [FeClL(diars)2]Y (L = CO, P(OMe)3, P(OPh)3; Y = SnCl3, BPh4) compounds. Using partial quadrupole splittings to calculate quadrupole splittings, all compounds are assigned the trans structure. From 57Fe centre shifts and quadrupole splittings, diars is found to be an appreciably poorer σ donor than analogous chelating phosphines, and a very similar σ donor and π acceptor to o-phenanthroline.

The ludwigite Co2FeBO5 has been studied experimentally using 57Fe Mössbauer spectroscopy and theoretically by means of the DFT+GGA calculations. The room-temperature Mössbauer spectra are composed of four quadrupole doublets corresponding...

Increasing Temperature

Mossbauer spectra of YC012B6 and NdCo12B6 doped with enriched 57Fe have been obtained at various temperatures between 4�2 K and room temperature. The spectrum of YC012B6 at 4�2 K indicates that the Co sublattice orders in the crystallographic basal plane. NdCo12B6 orders along or close to the crystallographic c-axis at 4�2 K and undergoes a spin-reorientation with increasing temperature until at ~55 K the magnetisation lies in or near the basal plane.
