Abstract
Heyrovskyite mineral Pb₆Bi₂S₉ from fumarole exhalations of the Kudryavyi volcano (Iturup island, Kurils, Russia) is studied by X-ray crystallography (Bruker Nonius X8 Apex with a 4K CCD detector, R = 0.0405). Unit cell parameters are: a = 4.1457(1) Å, b = 13.7421(5) Å, c = 31.5005(12) Å, V = 1794.6(1) Å³, Z = 4, d _x = 7.216 g/cm³, Cmcm space group, R=0.0405. The resulted structure is similar to the known structures of heyrovskyites from other deposits with some variation in the cation composition.

(sorry, abstract only. I don't have the article).
