Abstract
We report for the first time, the synthesis and X-ray diffraction studies of single crystals of BeF<inf>2</inf>. The crystals were obtained during the sublimation of amorphous BeF<inf>2</inf> under static reduced pressure. BeF <inf>2</inf> crystallizes in the chiral trigonal space group P3<inf>1</inf>21. A single-crystal X-ray diffraction study on these crystals shows that each of the Be atoms is bonded to four F atoms, and each of the F atoms is bonded to two Be atoms with associated Be-F bond distances of 1.5420(13) and 1.5471(13) Å, showing an almost regular tetrahedron. The infrared spectrum of these crystals recorded at room temperature shows distinct peaks around 770 and 410 cm <sup>-1</sup>. © 2010 American Chemical Society.
