Summary

The crystal structure of fluoborite, Mg3(F, OH)3(BO3), has been refined using X-ray data collected on an automatic diffractometer. The anisotropic refinement converged to a conventionalR of 0.029. The structural model proposed byTakéuchi as well as the space groupP 63/m have been confirmed.

Susammenfassung

Die Kristallstruktur des Fluoborites, Mg3(F, OH)3(BO3), wurde mit Röntgendaten, die auf einem automatischen Diffraktometer gesammelt worden waren, verfeinert. Die anisotrope Verfeinerung konvergierte auf ein konventionellesR von 0,029. Das vonTakéuchi vorgeschlagene Strukturmodell wurde bestätigt, ebenso die RaumgruppeP 63/m.
