Zusammenfassung
Die Verfeinerung der Kristallstruktur von Schafarzikit, FeSb2O4,a 0=8,59;c 0=5,91 Å, RaumgruppeP 4mbc-D 134h ,Z=4, bestätigte im wesentlichen die vonZemann gefundene Atomanordnung. Die Struktur konnte bei Verwendung von Weissenberg-Diffraktometerdaten aufR=0,056 verfeinert werden. Die Fe-Atome werden von sechs Sauerstoffen in Form eines Oktaeders umgeben, die Sb-Atome bilden mit drei Sauerstoffen eine flache trigonale Pyramide.
Summary
The crystal structure of schafarzikite, FeSb2O4,a 0=8.59;c 0=5.91 Å, space groupP 4mbc-D 134h ,Z=4, has been refined. The atomic arrangement agrees essentially with that determined byZemann. The refined structure, using Weissenberg diffractometer data, yielded a finalR value of 0.056. The Fe atoms are surrounded octahedrally by six oxygen atoms, the Sb atoms form with three oxygen atoms a flat trigonal pyramid.
