Abstract
Al2CO has a long‐range disordered structure based on the wurtzite lattice and a short‐range √3a, 2c superstructure. The long‐range atomic parameters were determined from the single crystal sharp diffraction data with Mo K radiation. The diffuse spectra, although very apparent on the single‐crystal x‐ray photographs, were inadequate to completely define the short‐range structure; however, the general features of this structure could be inferred and some analogies made to known structures which are wholly or in part wurtzite‐lattice superstructures.
