...) Abstract The crystal structures of fedorite from the type locality, the Turiy complex (Kola Peninsula, Russia) and the Little Murun complex (Sakha, Russia), have been refined from single crystals by CCD X-ray diffractometry. Both samples are triclinic, space group P 1̅; fedorite from Turiy has a 9.6300(7...
