I encountered a doubtful compound structure in this database: Cadmium Iodide (mp-582042). Among the 124 Cadmium Iodide structures, this one has the lowest energy above hull (most stable).
In the material project database, the crystal structure is “None” and the symmetry group is “”. According to wikipedia (https://en.wikipedia.org/wiki/Cadmium_iodide), however, the compound has the crystal type “trigonal” and the space group “P3m1”.
Does anyone know the reasons for the discrepancies? How can I get the original references or contact the authors?
Thank you in advance,
