CIF files of standard XRD data of High Tc superconductor cuprates including Cu,Tl 1223, Cu,Tl 1234 and Cu,Tl 1212 are missing in COD. i will be very grateful if anyone can provide me with them.
Hadi Mohamad Basma , if the structure like attached picture? attached also the CIF that generated from the references.
Tl share the same wyckoff with Cu (1a). That structure has Oxygen 9+delta.
Do you have a picture of Cu0.5Tl0.5Ba2Ca2Cu3O10-delta? because in those reference even if mentioned Cu1−xTlxBa2Ca2Cu3O10−delta the structure is same as one I've constructed.
