I'm usually using databases like the Springer Materials site or the free Crystallography Open Database to get crystal structure data. But none of these offers the possibility to search for all entries with a defined space group. I recently prepared a new compound and solved and refined the crystal structure. I would like to compare it to compounds known by literature to give the structure a name. It's quite common to compare structures to already existing ones. But I can't find any website that would give me the possibility to look for all entries with the same space group without knowing the elements.
Does anyone know a search engine for this specific problem?
