Abstract

Single photoswitchable molecules of (CN(3)H(6))(2)[Fe(CN)(5)NO] (GuNP) are embedded into nanopores of an SiO(2) xerogel. It is shown that it is possible to identify the structural motif (`fingerprint') of the embedded complex by analyzing neutron powder diffraction data in a limited Q range (Q < 37 nm-1) using the Debye approach. The structural study reveals that the pores are occupied by GuNP monomers with a fill factor of 60-80%. The mutual arrangement of the anion and cations in the GuNP monomer is slightly changed (similar to 1% elongation), while the bond lengths within the anion and cation are changed by less than 0.2% with respect to the single-crystalline form of GuNP.
