ResumoThe crystal structure of ReB 2 has been determined from powder data.The unit cell is hexagonal; a=2.900 and c=7.478A; there are two ReB 2 units per unit cell.The structure may be described in terms of alternating layers of rhenium and boron atoms; the former are planar, the latter are puckered.The two boron atoms show up clearly in difference maps (@z, 2x, Zobs.--@z, 2x, ZRe)" B-B bond lengths are 1.82 ~; shortest Re-B distance are 2.23 and 2.26 A.
