| 1922 Mineral. Mag. XIX. 348 Schafarzikite... Red, tetragonal crystals found with kermesite (and resembling this in appearance) at Pernek, Hungary, contain iron and phosphorus. 1955 M. H. Hey Index Min. Species (ed. 2) 271 Schafarzikite... Isostructural with artificial tetragonal FeSb2O4, but the one analysis approaches Fe5Sb4O11. 1975 Tschermaks Mineral. und Petrogr. Mitteilungen XXII. 236 The crystal structure of schafarzikite, FeSb2O4,..has been refined... The Fe atoms are surrounded octahedrally by six oxygen atoms, the Sb atoms form with three oxygen atoms a flat trigonal pyramid. |
