Crystal engineering beyond crystallography

Local structure of a switchable dielectric Prussian blue analogue

We have a longstanding interest in the family of Prussian blue analogues: metal ions bridged by cyanide linkers into a cubic framework that can accommodate many different guests in the pores. In a paper just published in CrystEngComm, arising from Helen Duncan’s PhD work, we use total neutron scattering measurements at ISIS to investigate one of these materials that contains planar imidazolium ions in the interstices.1 (more…)
