The cover picture shows the crystal structure of sodium borohydride dihydrate, NaBH 4 · 2H 2 O, 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 BH 4 – 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–H δ+ ··· δ– H–B bonding was accurately characterized. The structure of anhydrous NaBH 4 was also investigated by X‐ray diffraction on a single crystal. Vibrational properties of NaBH 4 · 2H 2 O 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.
