Abstract

The cover picture shows the crystal structure of sodium borohydride dihydrate, NaBH4·2H2O, determined from synchrotron diffraction on a single crystal. The European Synchrotron Radiation Facility (ESRF), shown in the lower left corner, provided the source of X-rays. The BH4– anion has a nearly ideal tetrahedral geometry. By applying the systematic correction to the positions of hydrogen atoms seen by X-rays, the geometry of the dihydrogen O–Hδ+···δ–H–B bonding was accurately characterized. The structure of anhydrous NaBH4 was also investigated by X-ray diffraction on a single crystal. Vibrational properties of NaBH4·2H2O and related substances were studied by IR and Raman spectroscopy. Details are discussed in the article by Y. Filinchuk and H. Hagemann on p. 3127 ff.
