IsoQuest: how unique is your structure?
Using the recently developed method IsoQuest, based on powder diffraction patterns, related structures can be found in the CSD. Below an example is given of a set of six CSD entries which are found using the IsoQuest method. For the corresponding PXRD patterns click here.
IsoQuest was presented at ECM22
