    www.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.

    www.sciencedirect.com/science/article/pii/S1386142516300397 Heterogenite 2H polytype presents a distinctive Raman signature, with a supplementary E 2g Raman mode observed at 1200 cm − 1 and related to the O–H bending vibration. This distinctive spectrum signature allows the use of Raman spectroscopy as an effective and fast technique to differentiate the two polytypes.

The rest (58.7%) represents misindexed points (CI < 0.1 and grain size < 2 pixels) or without solution. The main problem during this indexing results from the major modification of the polished section surface due to the thermal stress and the consecutive ...

    www.gecoproject.org/trace/nomentclature.php This latter author also revealed the existence of a hexagonal polytype, which he called "heterogenite 2H" (Deliens and Goethals, 1973). Since then, common heterogenite has been termed heterogenite 3R in mineralogical treatises, in order to distinguish it from the 2H polytype.

  • mp-743839: CoHO2 (hexagonal, P6_3/mmc, 194)

    materialsproject.org/materials/mp-743839 CoOOH crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Co3+ is bonded to six equivalent O2- atoms to form edge-sharing CoO6 octahedra. All Co–O bond lengths are 2.02 Å. H1+ is bonded in a linear geometry to two equivalent O2- atoms. Both H–O bond lengths are 1.21 Å. O2- is bonded in a 4-coordinate geometry to three equivalent Co3+ and one H1+ atom.
