title: Selective recovery of dynamic guest structure in a nanoporous prussian blue through in situ X-ray diffraction: a differential pair distribution function analysis.
abstract: We use in situ X-ray diffraction to obtain data suitable for differential PDF analysis, providing unique insight into the structure of weakly bound, dynamic N2 molecules in the Prussian blue system Mn3[Co(CN)6]2.x{N2}. The differential PDF shows a distributed orientation of N2 molecules constrained to sites centered about the (1/4,1/4,1/4) positions within the pores. The results show a subtle response of the framework to guest loading which corresponds principally to the perturbation of the Mn ion coordination.
