Abstract : The determination of the crystal structure of senaite has progressed to the point where a trial model consisting of all atoms has been defined. Plumboferrite has been examined and found to have the magnetoplumbite substructure. The structure of CoGeO3 has been refined in detail and the occurrence of polytypism in this compound is readily explained by the approximation to closest packing. Crystals of hogbomite, senaite, hibonite, and crichtonite from additional localities have been examined. (Author)
