  • Heterogenite: Mineral information, data and localities.

    zh.mindat.org/min-1885.html Abstract from Burlet et al. (2016): "Heterogenite is commonly referred in mineralogy literature as a cobalt oxy-hydroxide CoO(OH). However, detailed analysis of Raman and infrared spectra acquired on particularly well-crystallized natural samples of heterogenite suggests that the mineral can be characterized by a delafossite-type structure, with a general chemical formula ABO2.
  • Penroseite | Article about penroseite by The Free Dictionary

    encyclopedia2.thefreedictionary.com/penroseite The Shinkolobwe mine has yielded cattierite, carrollite, linnaeite, penroseite, siegenite, comblainite, oursinite and heterogenite (3R). In the lower part of the Shinkolobwe oxidation zone, siegenite rich in selenium is also found, in close association with penroseite (described below).

  • mp-1062939: CoO2 (trigonal, R-3m, 166)

    www.materialsproject.org/materials/mp-1062939 Lix0CoO2 is trigonal omega-like structured and crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three Lix0CoO2 sheets oriented in the (0, 0, 1) direction. Co4+ is bonded to six equivalent O2- atoms to form edge-sharing CoO6 octahedra. All Co–O bond lengths are 1.89 Å. O2- is bonded in a 3-coordinate geometry to three equivalent Co4+ atoms.
