THE CRYSTAL STRUCTURE OF BORON TRIFLUORIDE DIHYDRATE,
MISSISSIPPI VALLEY EXPERIMENT STATION BUREAU OF MINES ROLLA MO
Boron trifluoride dihydrate, prepared by intro ducing boron trifluoride gas into water and sub sequent fractional crystallization, was sealed in Pyrex glass capillaries. Crystals were grown in the capillaries by cooling with a stream of cold nitrogen crystallization was initiated by touch ing the capillary lightly with a piece of Dry Ice. The best crystal was used for all diffrac tion measurements the bc direction was along the capillary axis. The present structure de termination was undertaken to ascertain the true nature of this substance and to study the hydro gen bonding pattern. Author
