I am currently working on the adsorption of various species on beta NiOOH by using first principle DFT. I searched every open-access database but I was unable to find a proper CIF for NiOOH, what should I do now? Is there any open-access XRD database there? ( I found a CIF from the materials-project database but the structure is distorting after geometric optimization, and i think the cif is not up to the mark accuracy. I searced previous papers also but it was no help)
