Abstract

Groundstate and electronic excited state (MSI) of deuterated sodiumnitroprusside (Na2(Fe(CN)5NO)·2D2O) have been investigated by neutron diffraction as well as by optical and Mössbauer techniques. Significant structural changes occur predominantly in the O−N−Fe−C-bond. It has been shown, that the N−O bond-length is not the order parameter, as expected from other studies. We found an increase in the bond lengths Fe−N4 of 0.019(2) Å and N−O of 0.004(4) Å respectively, which is in qualitative agreement with changes determined by Raman spectroscopy and predictions based on diatomic correlations (Badger/Herschbach/Laurie). Additionally we observed a change in the Fe−C1 bond length of 0.012(3) Å in agreement with Raman meaurements.
